Repair or replace?
ReplaceReplace the 1769-L36ERMS if it will not boot, shows a solid red fault light, or has lost its program. Another Compact GuardLogix 5370 L3 controller takes the same program: download it, match the firmware, and the line is running again. Order the exact 1769-L36ERMS. The catalog number sets the 3 MB memory, and a different suffix changes it. The 1769-L36ERMS is on our shelf now and ships the same day for orders placed before 5:00 PM Central.
RepairRepair the 1769-L36ERMS when the fault is in the power section, a port or the status display rather than the processor core, or when the controller carries a firmware revision or validated project you cannot easily re-flash onto a different unit. The two 1769-L36ERMS symptoms we see most often are “Program lost on power cycle” and “Solid red OK LED (nonrecoverable major fault) at power-up”. If a replacement is already installed, repairing the failed 1769-L36ERMS gives you a tested spare on the shelf for the next failure. The 1769-L36ERMS repair is estimated $1,440.00, function-tested before return and covered by a 1-year warranty.
