Configure the settings of the controlling module to match your requirements. The
settings in these modules are as follows:
1 See “Calibration Pulsing Relay DO4,” below.
Ensure that the module’s Port setup register matches the meter’s output you want
to control. If the port you want to use does not appear in the Port setup register’s
list, that port is in use by another module. Edit the port setup register of the module
using that port and set it to
NOT USED – the port will then be available to other
modules.
Calibration Pulsing Relay DO4
Solid-state relay DO4 is factory configured for calibration pulsing and requires no
further setup. The Calibration Pulser module labeled kWh Pulser –D4 controls this
port. By default, the module is linked to the kW del+rec output of the Arithmetic
module labeled “del, rec” (in the Demand Framework). (This Arithmetic module is
linked to the MU Power Meter module’s MU kW tot output.) The port will output
a pulse for every 1.8 Wh accumulated (in
NORMAL or TEST mode). This is the same
pulsing rate as the middle LED on the front panel of the meter.
