S5-90U/S5-95U Function Modules
16.6.1 Installation Guidelines
Installing and Removing the Module
The counter module is plugged into a bus unit like other I/Os.
The counter module can only be plugged into slots 0 through 7.
Set the coding key to number 6 on the bus unit.
Installing or Removing the Sensor
Disconnect the 24-V DC power supply (terminals 1 and 2 of the terminal block) before connecting or
disconnecting the transducer cables.
!
Warning
Connecting or disconnecting the 5-V transducer cable while the module is energized can
cause damage to the sensor.
Connection of Pulse and Position Sensors
Connect pulse and position sensors on the front plate by means of a 15-pin sub-D female
connector. The correct cable connectors are listed in Appendix D. The module can supply the
sensors (5 V DC or 24 V DC).
Basically, all sensors can be connected if they fulfill the requirements of the system signals and
supply voltage. Sensors with OPEN-COLLECTOR outputs cannot be connected to the module.
The cable shield of the sensor cable must extend up to the module, the shielding may not be
connected to the connector.
