NOTE
If the negative active power or the positive and negative reactive power must be logged, use a measur-
ing transducer such as the Woodward UMT 1.
Pulse output
p.duration 0.00s
Pulse duration
0.04 to 1.00 s
The duty cycle of one output pulse is defined here.
Note: The pulse duration must be configured for compatibility to the kWh impulse.
It may be possible to configure overlapping impulses that may be recognized as a
continuous signal.
Pulse/kWh
Logic ----------
Output of the kWh-pulse
positive/negative
The output logic of the kWh-pulse can be either negative (the collector-output [ter-
minal 60/61] is de-energized for each positive kWh-pulse), or positive (the collec-
tor-output [terminal 60/61] is energized for each positive kWh-pulse).
Active energy
Pulse/kWh 000.0
Pulses per positive kWh
0.1 to 150.0
The quantity of pulses per measured kWh is defined here. The pulses issued by
this controller must be analyzed by an external control.
Example: If this parameter is configured as "
Pulse/kWh 020.00
" and 20 kWh
are measured the number of pulses that will be output will be 400 or 20 kWh ×
20 pulses/kWh = 400 pulses
RESET kWh
ON
RESET kWh measuring
ON/OFF
Enabling this parameter permits the kWh meter to be reset to zero by pressing the
"Select" and "Digit
↑
" buttons while in the automatic operating mode.
NOTE
The kWh-counter is reset by:
1. Verify the control is in automatic mode.
2. Verify that the kWh-counter is displayed in the lower line of the display.
3. Press and hold the "Select" and "Digit
↑
" buttons for at least 5 seconds.
After the counter has been successfully reset, the screens will display “
0000.0 kWh
".
