Supply voltage L+/M

You connect the supply voltage to terminals L+ and M on a light BaseUnit. For a dark

BaseUnit, the supply voltage of the module to the left is used. An internal protection circuit

protects the F-TM Count module from reverse polarity of the supply voltage. The F-TM Count

module monitors whether the supply voltage is connected.

Encoder supply

The encoder supply from the F-TM Count module provides 5 V DC encoder sensor supply

voltage. The encoder supply is only switched off during the following occurrences:

• There is a fatal error

• There is a firmware update in progress

Note

The F

-TM Count module can only support 5 V DC encoders using the module's inte

rnal sensor

supply. However, 10 to 30 V DC incremental encoders can be supported when externally

powered.
