6.2 Pulse Type and Value
The pulse outputs provided by the Din-Mon™ meter are VAR-Hour and Watt-Hour. The
pulse value is dependent on the amperage size of the meter. See the chart below for
the standard pulse values. Refer to section 10.2.6 Pulse Values for detailed
instructions on changing settings.

Din-Mon™ meters with "V3" sensor type support paralleling of up to 3 sets of 0.333V
type current sensors. Current sensors must be of the same type and model number.
The pulse values listed in the above table are based on 1 set of current sensors. When
multiple sets of current sensors are installed in parallel, the final pulse values will be
the product of the based pulse values times the number of sets of current sensors in
parallel.
Formula for calculating pulse value:
Pulse Value = (Base Pulse Value) x (Number of sets of Current Sensors in Parallel)
Example: Calculate the multiplier for a meter of 120/208 Volt, 3-Phase, 200 Amp, 3
sets of Current Sensors in parallel. Final pulse value is 11.71875 that is the result of
3.90625 multiplied by 3.
NOTE: The VAR-Hour pulse output contact can also be programmed to func-
tion as a Phase Loss contact. The normally open contact closes within
the meter due to the loss of any one of the three lines of voltage inputs
to the meter. The contact closure may be used to activate an audible
alarm, light, control coil, or other indicator device. This alerts appropri-
ate personnel to the loss of voltage. An emergency phone dialer may
also be programmed to send notification automatically by phone, text,
or pager. Alarming devices are to be supplied by others and are not
included with the Din-Mon™ meter.
NOTE: If the meter has more than 1 set of sensors in parallel, make sure to fac-
tor in the number of sets of sensors to the pulse values.
