Hi,
Im after some advice on the cotrol philosophy on the ccn network.
I have 2 x 30gh145 units both with CCN-OFF-LOCAL ON switches. One unit is the master with the flotronic master controller with an extra CCN-OFF switch. Found that the switch CCN/LOCAL was faulty and replaced with the switch connected to the master cotroller. According to the manual the switch works on resistence, 0 - 1,962ohmns for enable, >168,250ohmns for stop and 11,396 to 43,254ohmns for disable. So I put a 1ohm resister across terminals for an enable signal, but all i can see is CCN off. The bms signal is a 24v signal to the master controller and this is ok, I cant understand why I am not seeing a CCN on display. We have same set up elsewhere on site and have cross referenced with them. allseems the same. I do not know how the ccn decides what comes on and when, so any insight greatly appreciated. sorry for the long post.:confused:
