Troubleshooting Tips & Tricks*

Problem

Possible Cause & Solution

Operator Interface (Control Panel) shows "Micrologic DF-1 Attempting Link" and scale will not enter run mode.

Control wires may be loose or PLC may be faulted.

Solution: Unplug scale. Open control cabinet. Check connection of gray wire that connects the Operator Interface to the PLC. If connection is tight, then plug scale in and check LED (indicator lights on PLC). POWER and RUN lights should both be "on" and green. Fault Light should be "off". If Fault Light is "on" and red, try the following two-part process to return the PLC to RUN mode:

Part 1: (Clear fault)

Press: MENU

Press: MODE (disregard "Access Denied" message)

Press: 7734 (ENTER)

Press: 3

Press: 4

Press: 1

Press: MENU

Part 2: (Run mode)

Press: MENU

Press: MODE

Press: 7734 (ENTER)

Press: 3

Press: 2

Press: 1

Press: MENU

This should return the PLC to RUN mode, assuming nothing is actually broken...

* Machine troubleshooting & repairs should only be attempted by a qualified mechanic or electrician. Power should always be disconnected prior to troubleshooting.
