So if anyone out there is running a Honeywell C-300 with experion. We recently had to replace a bleach pump that runs with a permissive from the DCS (DO). For some reason we are throwing an initialization error and are not able to give the permissive on a set of contacts. Typically this would mean that somewhere along the lines we have an open circuit as the DCS is not seeing a good loop/ feedback or there is not enough resistance through the loop. We have megged the wires and all are good, we can source the signal from a fluke and the pump will start running as it should.
When we installed the first pump we had to add a 2.2K ohm resistor into the circuit and that fixed the issue then. However, this time we are not having success. Whatever is going on I am not getting my 24 VDC out of the DCS point at all and we also tried moving channels with to no avail. Kind of out of ideas on what the issue could be so any ideas or spitballs at all would be greatly appreciated. TIA
