How to set ACK input (MC-3020D)
Use the connectors J3 to J6 on the MC-DIN Board (24P0116) to set the ACK input for
ACK1 to ACK8 as shown below.
• Input circuit for voltage input
• Input circuit for contact input
Note 1:
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).
Note 2:
For analog input, see paragraph 2.7.2
