F03 - Low pressure alarm (LOP):When the evaporation pressure falls below this value the electronic expansion valve gradually opens to increase the pressure in the system. This process will happen until the pressure reaches the value set in this function.

F04 - High pressure alarm (MOP):When the evaporation pressure rises above the value configured in this function, the controller gradually closes the electronic expansion valve to keep the pressure below the established value. This protection is intended to avoid the superheating with an extremely low value causing the return of liquid to the compressor.

F05 - Static gain (Kp):Proportional Gain: Acts directly by opening or closing the electronic expansion valve in relation to the variation of the temperature in a proportional way. The value is a multiplying factor that establishes the relationship between “Valve steps / oC“.Proportional Action: Proportional Gain x (Read - setpoint).

Description

time



F07 - Derivative time (Td):This is the response time in relation to the variation rate of the superheating in the system. It helps to minimize the overshoot caused by the integral time.

F08 - Cooling fluid type:This function allows selecting the type of cooling gas that will be used. It is possible to select the gas in accordance to the table below:

F09 - Total number of valve steps:This function defines the number of steps specified for the electronic expansion valve (EEV).

NOTE: This function cannot be changed.

F10 - Operating speed (steps per second):This function defines the number of steps per second.

NOTE: This function cannot be changed.

F11 - Initial valve opening value (%):This function defines the opening value of the electronic expansion valve when starting the control and acting together with F12.

F12 - Delay time for superheating control:Time for which the electronic expansion valve will remain open as defined in F11. See item 6 - operating mode.

F13 - setpoint:This is the reference value for superheating control.

F14 - Critical alarm:When the temperature drops below this value, the critical alarm is triggered and the message [ASHC] .

F15 - Low alarm:When the temperature drops below this value, the low alarm will be activated and will gradually close the electronic expansion valve .

F16 - High alarm:When the temperature rises above this value, the high alarm will be activated and will gradually open the electronic expansion valve .

F17 - Operating setpoint:It is the control temperature for the normal operating mode. The compressor will be switched off when the room temperature drops below the value configured in this function.

F18 - Economy setpoint:It is the control temperature when the economy operating mode is active. The compressor will be switched off when the room temperature drops below the value configured in this function.

F19 - Minimum setpoint allowed for the user:It is a threshold aimed at preventing an exceedingly low temperature setpoint from being adjusted inadvertently.

F20 - Maximum setpoint allowed for the user:It is a threshold aimed at preventing an exceedingly high temperature setpoint from being adjusted inadvertently.

F21 - Differential control (operating setpoint):It is the temperature difference between SWITCHING OFF and SWITCHING ON AGAIN the refrigeration in the normal operating mode.Example: You want to control the temperature at 4.0 °C with a differential of 1.0 °C. Then the refrigeration will be switched off at 4.0 °C and switched on again at 5.0 °C (4.0 + 1.0).


(EEV)

F22 - It is the temperature difference between SWITCHING OFF and SWITCHING ON AGAIN the refrigeration in the economy operating mode.

F23 - Digital input operating mode:It allows choosing the way the digital input will operate:[,,,0]- disable[,,,1]- door alarm (NC contact)[,,,2]- (NO contact)

F24 - Intensity of the digital filter applied to the room sensor (S1):It defines the intensity of the digital filter, which is aimed at increasing the response time of the controller for a quick change in the temperature measured by S1, i.e. increasing the thermal inertia of the sensor. The higher the value adjusted in this function, the longest the response time of sensor S1.A typical application requiring this filter is a freezer for ice cream or frozen goods, because a hot air mass reaches the sensor directly when the door is opened causing a quick rise in the indication of the measured temperature, frequently causing the compressor to be activated unnecessarily.

F25 - Room temperature offset - S1:It allows compensating possible deviations in the room temperature reading caused by the replacement of the sensor or changes in the cable length.

Differential control (economy setpoint):

door alarm

F26 - Evaporator temperature offset - S2:It allows compensating possible deviations in the evaporator temperature reading caused by the replacement of the sensor or changes in the cable length.

F27 - Suction line temperature offset - S3:It allows compensating any deviation in the suction line temperature reading caused by the replacement of the sensor or changes in the cable length.

F28 - Type of defrost (0= resistance / 1= hot gas / 2= natural):[,,,0]- Electric defrost (by resistance), where only the defrost output is activated.[,,,1]- Defrost by hot gas in plug-in systems (with reversing valve), where the compressor and defrost outputs are activated. The compressor is compulsorily switched off before starting the defrost cycle, and the minimum compressor off time is observed before starting it (in order to reduce water hammer effect of the cooling fluid in the pipes).[,,,2]- Natural defrost, the compressor and defrost output remain off.

NOTE: The fan output will depend on the parameters configured in functions F23 and F42.

F29 - Condition to start the defrost (0= time / 1= temperature):[,,,0]= Defrost by time[,,,1]= Defrost by temperature

F30 - Interval between defrosts:It is the time for which the compressor will be switched on and off by the room temperature and it is counted from the moment the fan is switched on after the stage of fan-delay (return of the fan after draining).

Warning: Defrost will only be started if the temperature in the evaporator sensor is below the value adjusted in F34 (evaporator temperature to end the defrost) and F35 (room temperature to end the defrost).

F31 - Evaporator temperature to start the defrost if F29=1(defrost by temperature): When the evaporator temperature reaches the value set in this function the controller starts to count the confirmation time to start defrosting.

F32 - Time to confirm a low temperature (S2) to start the pre-defrosting if F29=1 (defrost by temperature):When the evaporator temperature drops and then reaches the value set in F31, the controller starts to count the confirmation time to start the pre-defrosting. During this step, if the temperature remains low the pre-defrosting is started. Otherwise, if the temperature rises above the configured value, the system gets back to the refrigeration step.

F33 - Time to collect the gas before starting the defrost:When starting the defrost the controller will keep only the fan on for this time to use the residual energy in the gas.

F34 - Evaporator temperature to end the defrost:If the evaporator temperature (S2) reaches the adjusted value, the end of defrost will be by temperature, which is the desirable way. Thus the defrost process is optimized, resuming the refrigeration as soon as the evaporator is clean.

F35 - Room temperature to end the defrost:If the evaporator temperature (sensor S2) reaches the adjusted value, the end of defrost will be by temperature, which is the desirable way. Thus the defrost process is optimized.

F36 - Maximum time without defrost if F29=1:It acts as a safety time when it is configured to defrost by temperature and the evaporator temperature does not reach the value set in F31. This function defines the maximum time the controller will remain without perform defrosting.

F37 - Maximum defrost time:For safety reasons, if the evaporator temperature does not reach the value adjusted in F35 and F34, the end of defrost will take place by time. Whenever this happens, a point will keep flashing in the lower right corner of the display or Sitrad screen.

F38 - Temperature indication (S1) locked during defrost:This function configures if the room temperature displayed by must be frozen during (and after) a defrost (both in cooling mode and heating mode). The purpose of this function is to avoid the visualization of a variation in the room temperature due to the defrost, and the operation of the function will depend on the type of defrost being performed:Defrost:[,,no]- Function disabled (S1 temperature is never locked as a function of the defrost)[,,,0]- Upon starting the defrost, the controller stores the room temperature and freezes it on the display. The indication will remain frozen until the defrost is finished.[,,,1]to [,,60] - Upon starting the defrost, the controller stores the room temperature and freezes it on the display. The indication will remain frozen until one of the following conditions happen: If the temperature reaches a value below the one registered in the beginning of the defrost or if the time configured in this function has expired. This time starts to be counted when the defrost finishes.

F39 - Defrost when the instrument is powered on:It allows performing a defrost when the controller is powered on, for example when the electric power returns (in case of power fault).

F40 - Draining time (defrost water dripping):It defines the dripping time so that the last drops of water in the evaporator have flown when the controller finishes the defrost. All outputs remain off. If it is not required in this step this function must be configured with 0 (zero).

F41 - Fan operating mode - normal mode:F42 - Fan operating mode - economy mode:0 - Automatic: The fan is constantly on while the compressor is on. When the compressor is off, the fan will cycle according to the times configured in F43 and F44.1 - Continuous: The fan is always on.2 - Dependent: The fan will be turned on together with the compressor.

time

F60 - Door open time for audible alarm:If the digital input is configured as door (F23) in this function the time to sound the alarm (buzzer) will be counted.

F61 - Inhibit time alarm by temperature:The purpose of this function is to inhibit the alarm for some time due to an occasional temperature rise. The alarm is disabled during the defrost, draining and fan-delay operations.

F62 - Inhibit time alarm upon power up:The audible alarm remains off during this time waiting for the system to achieve its steady state.

F63 - Defrost end alarm:When the defrost operation is ended by time instead of by temperature, the user can be warned by a flashing point in the lower right corner of the display ( ).

F64 - Turning off the control functions:It allows switching off the refrigeration, fan, and defrost outputs after the electronic expansion valve is fully closed.

F65 - Equipment's address in the RS-485 network (serial communication):Each device connected to the RS-485 network must have a unique address different from the others such that the computer can identify the equipment.

Warning: Make sure that there are no devices with the same address to avoid communication problems.

7. OPERATING MODE (MANUAL / AUTOMATIC)

A calibration of the step motor of the electronic expansion valve (EEV) is performed when the is initialized. Thus the Sitrad will indicate it is initializing in the status field. Then the

controller will open the electronic expansion valve according to the value specified in function F11 (initial valve opening value) and remain in that position for the time specified in F12 (delay time for superheating control). After this procedure the controller adjusts the control according to the manual mode (F5=0, F6=0, and F7= 0) or automatic mode (PID control).

Note 1: In manual mode the electronic expansion valve keeps the value of function F11 (initial opening value of the electronic expansion valve ) fixed during the cooling process. The valve is closed during the other processes.

Note 2: The electronic expansion valve acts together with the compressor. Upon shutdown the valve is closed independently of the superheating value.

When the compressor is switched on again the electronic expansion valve will open until the value specified in function F11 (initial opening value of the electronic expansion valve ) so the cooling fluid is allowed to expand as soon as the compressor is back in operation, also observing the time configured in function F53 (minimum compressor off time).

F46 - Fan stop due to high temperature in the evaporator:This aims at switching off the ventilation of the evaporator until the room temperature approaches the temperature provided for in the cold storage installation design, thereby avoiding high temperatures and discharge pressures that can damage the compressor. If the evaporator temperature exceeds the adjusted value, the fan is switched off, being switched on again with a fixed hysteresis of 2 °C below this value. It is a valuable resource when, for example, a cold storage installation is started up after several days of inactivity, or when a walk-in chamber or display is replenished with warm goods.

F47 - Evaporator temperature (S2) for the fan to return after draining (fan-delay): The fan-delay cycle is started after the draining phase. The refrigeration (REFR) is activated immediately because the room temperature is high but the fan is activated only after the temperature on the evaporator drops below the adjusted value. This process is required to remove the heat that already exists on the evaporator as a result of the defrost to avoid throwing it in the environment.

F48 - Maximum time for the fan to return after draining (fan-delay):For safety reasons, if the evaporator does not reach the value adjusted in F47 or if the defrost sensor (S2) is disconnected, the fan will return in the time adjusted in this function.

F49 - Maximum open door time for instantaneous defrost if F23 0:If the door is kept open longer than the time defined in this function, an instantaneous defrost will be performed provided that the evaporator temperature (sensor S2) is lower than F34 (evaporator temperature to end the defrost) and the room temperature (sensor S1) is lower than F35 (room temperature to end the defrost).

F50 - Door open time to switch off COMP. and FAN if F23 0:For safety reasons, if the door is kept open longer than the time defined in this function, the compressor and fan will be switched off.

NOTE: Function F45 has priority over F50.

F51 - Door closed time for activating the economy mode if F23 0:If the digital input is configured as door, the economy mode is activated if the door remains closed longer than the time set in this function.

F52 -

F53 -

F54 - Compressor on time in case of error in S1:If the room sensor (sensor S1) is disconnected or out of range, the compressor will be switched on according to the time configured in this function.

F55 - Compressor off time in case of error in S1:If the room sensor (sensor S1) is disconnected or out of range, the compressor will be switched off according to the time configured in this function.

F56 - Compressor delay after powering up the controller:When the instrument is switched on it will remain with its control disabled, delaying the beginning of the process. During this time the controller only works as a temperature indicator. The purpose is to avoid peaks of electric power demand after a power fault when many devices are connected to the mains. To do this, simply set different times for each device. This delay may be either for the compressor or the defrost (when the defrost on startup is configured).

F57 - Maximum compressor on time without reaching the setpoint:The message [Alrc] is displayed when the compressor remains on longer than the time set in this function without reaching the setpoint.

F58 - Low room temperature alarm:It is the room temperature (S1) below which the instrument will activate the low temperature alarm. The indication can be visual and audible in ([Alo,]and Buzzer), or even through Sitrad (temperature out of range).

F59 - High room temperature alarm:It is the room temperature (S1) above which the instrument will activate the high temperature alarm. The indication can be visual and audible in ( and Buzzer), or even through Sitrad (temperature out of range).

Minimum compressor off time:It is the minimum time the compressor will remain off, i.e. the length of time between the last stop and the next start up. It is aimed at relieving the discharge pressure and increase the service life of the compressor.

Minimum compressor on time:It is the minimum time for which the compressor remains switched on, i.e. the length of time between the last start up and the next stop. It is aimed at avoiding high voltage surges in the power lines.
