6. INSTALLATION AND CONNECTIONS
The inputs and outputs of the GSM-20 CPU board are isolated in group and theinputs of the expansion boards and inputs accomplished with DIN modules are notisolated. The serial connectors RS232 and parallel with it RS485 (SER1) andRS232 (SER2) are not isolated from PLC’s internal voltages. To ensure properfunction of GSM-20 the installation circumstances must be carefully considered.
Operating temperature - 35 to + 55°C (with IP65 enclosure and power on)
Moisture, corrosive gases, liquids and conductive dust must not be present where PLC boards are installed.
The PLC boards don't resist heavy vibration very well.
The distance from electromagnetic field generating devices, such as electricmotors, switch gear, thyristors, welding equipment, switched power supplies and power converters/inverters must be adequate.
PLC boards are quite immune against powerfull light sources.
If some item above or any other envinronmental feature may cause errors to PLCfunction it is advisable to install the PLC in the steel plate enclosure. It is alsoad-visable to install possible auxiliary input/output relays fuses and power units intheir own enclosure near the PLC. All the contactors connected to PLC have tobe equipped with RC protection devices and the 24 VDC control relays withextinguish diodes.
6.2 Field wiring
6.2.1 Earthing/grounding
The metal parts of the PLC enclosure must be connected to the plant’s logicground.
6.2.2 Power supply connections
Normally no functional grounding is necessary when 24 volt floating voltage systemis used with the PLC’s power supply connection. It is important that the 24 voltwiring is carefully kept isolated from ground level and 230 volt supply voltages.
The CPU board, GSM-20 receives the +24 V DC supply voltage from an external,isolated power supply unit (such as AL 9624/3.5 or AL 9624/8). The controllerconverts this to the voltages it requires.
6.1 Environmental requirements
AutoLog GSM-20 Hardware Manual
FF-Automation Oy
31
Expansion boards DI16, RIO8 and RO16 receive their supply power from CPUboard through the bus cable. Input board DI16 and the input part of the boardRIO8 doesn’t need any external power supplies. The control/operating power forthe controlled loads must be taken from external supply units.
6.2.3 Digital inputs
The digital inputs are isolated in group on GSM-20 CPU board. Externally poweredpotential free contacts or PNP type inductive/capacitive sensors may be connectedto PLC. The supply voltage for the PNP sensors is normally taken from external I/Opower unit.It is recommended to use twisted pair shielded cables in input wiring. The cablingshould be installed separately from the 230/400 VAC power cabling. The cableshields may be connected to logic ground only at one point, normally at the end onthe PLC enclosure. If there is heavy electromagnetic disturbance, the PLC’sunisolated inputs can be isolated from field equipment with relays or optoelectronicmodules.Look at chapter 6.3.3.
6.2.4 Digital outputs
The digital outputs are isolated in group on GSM-20 CPU board. Only low powered24VDC control relays, LED indicating lights or 24 volt indicating lights may beconnected to CPU outputs. The supply voltage for loads is taken from external I/Opower unit.It is recommended to use twisted pair shielded cables in output wiring. The cablingshould be installed separately from the 230/400 VAC power cabling. The cableshields may be connected to logic ground only at one point, normally at the end onthe PLC enclosure. If there is heavy electromagnetic disturbance, the PLC’sisolated outputs can be double isolated from field equipmnet with relays oroptoelectronic modules. Look at chapter 6.3.3.
6.2.5 Analog inputs/outputs
The analog inputs and outputs are unisolated in GSM-20 CPU board. If activetransducers are used, it should be checked that the output circuits of the transdu-cers are galvanically isolated from it’s supply voltages. If you can’t be sure of iso-lation, it is advisable to furnish the transducer with an external galvanic isolator.The supply power for passive transducer is normally taken from PLC’s power unit.The impedance of GSM-20’s analog milliamper input is 46Ω.It is recommended to use twisted pair shielded cables in output wiring. The ca-bling should be installed separately from the 230/400 VAC power cabling. The ca-ble shields may be connected to logic ground only at one point, normally at theend on the PLC enclosure. The analog modules are needed for analog inputs.The analog modules are extra equipments (Look chapter 7. LIST OF PROD-UCTS). RMS analog input modules requires 12 VDC power to function. Look atpage 6.5 section Power supply connection for expansion boards and DINmodules how to check that 12 VDC power is connected.

6.3.3 Optoelectronic / relay isolation of inputs and outputs
Since the inputs and outputs (excluding relay outputs) are not isolated on GSM20boards, it is advisable to provide external isolation in an environment prone todisturbances. A suitable solution is the use of PHOENIX digital optical inputinterface modules and relay output modules. The Modules protect the PLC againstthe static discharges and cut the circulating fault currents. The modules aremechanically fully protected DIN rail units.

6.4 Analog inputs
There are 0 - 8 individually adaptable analog inputs that can be used for themeasurement of temperature, current or voltage signals. The number of availableanalog inputs is defined according to adapter modules. Part or all of analog inputscan be defined as digital inputs by adapter modules. Analog inputs are not isolatedfrom PLC vlotages. Every measured signal / range needs its own individualadapter module.(Look chapter 7. LIST OF PRODUCTS).
6.4.1 Connection examples
Because of the low signal levels to be measured, shielded twisted-pair cablesshould be used. The shield should be grounded at one end only in order to avoiddegradation of accuracy by external disturbances.

In order to make the adjustment of thePt100 input as accurate as possible overthe measurement range, different adjust-ment points have to be used. Instead ofadjusting the OFFSET at the lowest valuewe use a 10% point as the adjustment pointfor the low end of the measurement range.In the same way we use the 90% point asthe adjustment point for the high value. Thisincreases the overall accuray.The curve in picture is exaggerated.
6.4.2 Temperature measurement with a PT100 sensor
The Pt100 sensor is nonlinear. The following temperatures corresponds tothe resistance values given in the table (DIN 43 760) below:
The GSM20 board has two (12 bit) analog outputs. The analog outputs arevoltage outputs (0 ... 5V or 0 ... 10V).

6.6.3 GSM-20 and CNV-1 Signal level converter board
It’s possible to isolate the serial connections by using external conversion modulese.g. CNV1. The CNV-1 provides isolation of the serial communication signal andconversion of the voltage level of the signal. The signal level can be +5 V,RS-232C or RS-422/485. Isolation is neccessary when the devices communicatingthrough the line are fed from power sources at differing potentials. The output ofthe RS-422/485 inter-face is in a high-impedance state when not transmiting, andseveral PLC’s can thus be connected to the same bus. The communication cableto the CNV-1 board comes from the RJ45 (RS232) connector of the GSM20.
The CNV-1 signal level converter board is described in more detail in a separateinstruction: CNV-1.
The figure below shows an example of the use of the CNV-1: the connection ofGSM-20 controller via an RS-232C interface to RS422 board.
