2.6 Logic Alarm Cable Connection and Functions
This section describes how to connect the logic alarm cables and the functions of cable.
During wiring, conrm that the signal's supply source is turned OFF to prevent electrical shocks.
Also, position the GL240 input cable away from any power lines and ground cables.
The Input/output cable for GL (B-513: Option) enables logic/pulse input, external trigger input, and alarm
signal output.
Connect the Input/output cable for GL (B-513: Option) to the external input/output terminal as shown below.
