P.br Fault, Unable To Remove This Alarm

Hi there,

I am having some troulbe with a 2404f controller. the units are repeatedly flashing with p.br on the setpoint area of the display. i have found that under 2A parameters under I.D heading it is stating 'pot1'. there is no module plugged into slot 2 so im not sure why? I am unable to change the parameter in any access level.

The only module used is in slot 1 and is an isolated dc output module.

i have compared the controller and its parameters to a working controller and all parameters and modules are the same apart from is says 'pot1' under id heading in 2A with no card plugged in.

there is no position feedback from the motorised valves.

Any help would be greatly appreciated.

Cheers

Dan
