Remote key facility (Optional):
The remote key facility allows the Micro 4000 to be fitted with up to 3 external remote keys. These remote
keys duplicate the key function as designated on the front facia panel. Configuration of the remote keys is
carried out in the service mode and allow’s the key function to be local (ie:operation from the front facia) or
remote. If the key is allocated as remote then the key function is disabled on the front facia panel.
Allocation of remote keys
Print key -------> spec 23 (off = internal , on = remote)
Semi-auto tare key -------> spec 24 (off = internal, on = remote)
Start key(F3) -------> spec 25 (off = internal, on = remote)
Connection of a remote key is very simple and consists of a two wire momentary push button switch as
shown in the circuit below. This circuit should be duplicated for each remote key switch fitted. |
