7.2 Functions of the inputs and outputs
110 Manual, 08/2017, L1V30368969104A-02
Pin 316 - O: Command for transfer to position O
Closing of this contact has the result that the transfer switching equipment is switched to the
O position. This command is activated if the following requirements are met:
● The switch on the motor operator is in the "Auto" position
● Contacts 312, 316 and 317 are connected to one another
● Contact 313 is open
Pin 317 - COM: Common control terminal for inputs 312-316
Input 317 is used as the common control terminal for inputs 312-316.
