Connector J5
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.
• 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 page 2-59.
