Communication
The communication modules are connected via a 6-pole reaction-free plug, ena-
bling them to be installed or replaced at any time.
Compliance with ESD regulations must be ensured
.
The UH50.. meters are equipped with an optical interface as standard. Also, up to
2 of the following
communication modules
can be used for remote readout:
Pulse module
WZU-P2/WZU-P2L
CL module
WZU-CL
M-bus module
WZU-MB, WZU-MB-G4
M-bus module with 2 pulse inputs WZU-MI
Analog module
WZU-AM
RF module, 433 MHz
WZU-RM, WZU-RM-EXT
RF module, 868 MHz
WZU-RF, WZU-RF-EXT
GPRS module
WZU-GPRS, WZU-GPRS-ANT
GSM module
WZU-GM
These modules have no impact on consumption metering and can therefore be
replaced at any time without having to destroy the security seal
.
Within 30 seconds after mounting (in case of the analog module up to 2 minutes),
the meter detects automatically the module used and is then ready for
communication or for delivering pulses.
The type of module used can be displayed within the service loop (loop 4), depend-
ing on the parameter settings made for the display.
