Kwh Pulse Output - Honeywell HVAC400x Applications Manual

HVAC400X – APPLICATION MANUAL
If it is necessary for the motor to operate always FORWARD or always REVERSE in Fire Mode, make a selection
of the correct digital input.
DigIn Slot0.1 = always FORWARD
DigIn Slot0.2 = always REVERSE
P3.17.7 FIRE MODE PRESET FREQUENCY 1 (ID 15535)
You can use this parameter to set the preset frequency for Fire Mode.
V3.17.10 FIRE MODE STATUS (ID 1597)
This monitoring value shows the status of the Fire mode function.
V3.17.11 FIRE MODE COUNTER (ID 1679)
This monitoring value shows the number of the fire mode activations.
NOTE: You cannot reset the counter.
P3.17.12 FIRE MODE RUN INDICATION CURRENT (ID 15580)
You can use this parameter to set the current limit for digital output run indication signal.
This parameter has only effect if 'Run indication' is selected as the option for a relay output and the Fire mode is
active. The 'Run indication' relay output functionality tells quickly if current is supplied to the motor during a fire.
The value of this parameter is the percentage counted from the motor nominal current. If there is a fire and the
current that is supplied to the motor is more than the nominal current times the value of this parameter, the relay
output closes.
For example, if the Motor nominal current is 5 A, and you set the default value 20 % for this parameter, the relay
output closes and Fire Mode activates when the output current goes to 1 A.
NOTE: This parameter does not have an effect if the Fire mode is not active. In normal operation, if you select
'Run indication' as the option for a relay output, the result is the same as when 'Run' is selected for the
relay output.

kWh Pulse Output

P3.18.1 KWH PULSE LENGTH (ID 15534)
You can use this parameter to set the length of kWh pulse in milliseconds.
P3.18.2 KWH PULSE RESOLUTION (ID 15533)
You can use this parameter to set the kWh interval between triggering of pulses.
