Why are TER and ERR on solid on my TSX Premium P57104?

Published date: 25 March 2019

Issue
The TER and ERR indicators are on solid and will not go away regardless of reset or power cycle.

Product line
Modicon Premuim - low end only

Resolution
The cover of the top slot actually triggers a switch that needs to be made. Whether or not you have a card in the slot, the cover must be firmly in place or those two lights come on solid. If a good unaltered cover is firmly in place and the lights stay on, your CPU is suspect. This does not apply to the high end CPUs as then use a different PCMCIA slot design.
