How to set ACK input (MC-3020D)
• Input circuit for voltage input
• Input circuit for contact input
Connector J3
Use the connectors J3 to J6 on the MC-DIN Board (24P0116) to set the ACK input for
ACK1 to ACK8 as shown below.
Note: The input must not exceed the range of the input voltage, to prevent
malfunction.
-Setting for voltage input: 21.6 V to 31.2 V
-Setting for contact input: Voltage cannot be input (contact signal only).
