How to set ACK input (MC-3020D)
Use the connectors J3 to J6 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 malfunc-
tion.
• Setting for voltage input: 21.6V to 31.2V
• Setting for contact input: Voltage cannot be input (contact signal only).
