Resolved Issues
The a VIEWMARQ displays shows Interlock System Error: xxxxxxxx, where the xxxxxxxx is an 8-bit binary number, if there is a state that should not exist. The error was that the specific 8-bit combination was not programmed into the VIEWMARQ display. All 255 possible combinations of the 8-bit signal must be programmed individually, therefore is a combination was not considered or overlooked, a false error will occur.
The VIEWMARQ display either shows the wrong status or an error status. This error was caused by incorrect wiring in the interlock system aggregator panel between the relays. This could also be caused by a faulty relay, bad power supply, or other downstream issues.
