SYSTEM DIAGNOSTIC
FACILITIES
The system diagnostics are
available for all parts of the
system, including any remote
power supplies fitted.
The diagnostic resolution is:
VOLTS: 0·1
CURRENT: 0·01A
System voltage and current –
at End Station and at each
individual power supply.
System voltage – at each
Keypad / Tag Reader
Battery condition and charge
current – at End Station or any
remote power supply (under
development).
Display inputs – current status
of all inputs connected to a
single system component,
displayed in real time
iD Diagnostics –
Slow scan, line
current, biscuit diagnostic current
– at End Station and each ZEM.
Calibration – permits calibration
of End Station PSU and iD output
voltages, using a calibrated
meter.
