2.11 Logic Alarm Cable Connection and Functions

This section describes how to connect the logic alarm cables and the functions of cable.
During wiring, confirm that the signal's supply source is turned OFF to prevent electrical shocks.
Also, position the GLT400 input cable away from any power lines and ground cables.
The input/output cable (B-513: option) enables logic/pulse input, external trigger input, and alarm signal
output.
Connect the input/output cable (B-513: option) to the external input/output terminal as shown below.
