1.05 COMMON FUNCTIONS
A. Common functions that are generally applicable to all loops or to many similar loops are
described below. These functions are not repeated in the descriptions for each individual
control strategy. The following general control system functions shall be provided:
1. All equipment motors will have FAIL TO START and FAIL TO STOP alarms. Once the
start control criteria are met a START/STOP COMMAND will be generated and the
motor should start. Once the START/STOP COMMAND has been issued the FAIL TO
START ELAPSED TIME will start. The PLC will expect to see a RUN INDICATION
before the Fail to start Timer has reached the FAIL TO START TIME DELAY SET
POINT. Failure to receive the Run Indication in the allotted time will trigger a FAIL TO
START alarm. Once the stop control criteria are met the START/STOP COMMAND
will be removed and the motor should stop. Once the Start/Stop Command has been
removed the FAIL TO STOP ELAPSED TIME will start. The PLC will expect to lose
the Run Indication before the Fail to Stop Timer has reached the FAIL TO STOP
TIME DELAY SET POINT. Failure to lose the Run Indication in the allotted time will
trigger a FAIL TO STOP alarm. The FAIL TO STOP and FAIL TO START alarms may
only be reset by the HMI ALARM RESET pushbutton on the HMI. The delay set points
will accept values from 0-9999 seconds.
2. All motors that are controlled by VFD’s will have SPEED CONTROL FAILURE alarms.
The SPEED CONTROL and SPEED CONTROL INDICATION will be compared once
the Run Indication has been received. The two values must be within the SPEED
DEVIATION SET POINT or a SPEED CONTROL FAILURE alarm will be generated.
This alarm may only be reset by the HMI ALARM RESET pushbutton on the HMI.
The SPEED DEVIATION SET POINT will accept values from 0-100%.
3. All valve motors with Open and Closed indication will have the following. Once the
Open pushbutton is selected an OPEN COMMAND will be generated and the motor
should run in the open direction. Once the Open Command has been issued the FAIL
TO OPEN ELAPSED TIME will start. The PLC will expect to see a VALVE OPENED
INDICATION before the Fail to Open Timer has reached the FAIL TO OPEN TIME
DELAY SET POINT. Failure to receive the Open Indication in the allotted time will
trigger a FAIL TO OPEN alarm. Once the Close pushbutton is selected a CLOSE
COMMAND will be generated and the motor should run in the close direction. Once
the Close Command has been issued the FAIL TO CLOSE ELAPSED TIME will start.
The PLC will expect to see a VALVE CLOSED INDICATION before the Fail to Close
Timer has reached the FAIL TO CLOSE TIME DELAY SET POINT. Failure to receive
the Closed Indication in the allotted time will trigger a FAIL TO CLOSE alarm. The
FAIL TO CLOSE and FAIL TO OPEN alarms may only be reset by the HMI ALARM
RESET pushbutton on the HMI. The delay set points will accept values from 0-9999
seconds.
4. When a motor generates an overload or VFD Fail Indication input a FAIL INDICATION
alarm will be generated.
5. All modulating valves and dampers will have POSITION CONTROL FAILURE alarms.
The POSITION CONTROL and POSITION INDICATION will be compared. The two
values must be within the POSITION DEVIATION SET POINT or a POSITION
CONTROL FAILURE alarm will be generated. This alarm may only be reset by the
HMI ALARM RESET pushbutton on the HMI. The POSITION DEVIATION SET
POINT will accept values from 0-100%.
