How to calculate a suitable
1.Convert Max. power (eg. kW) to Max. energy per second
Example
Max. power = 5 kW
Max. energy per hour = 5kWh
Max. energy per second = Max. energy per hour (kWh) / 3600
Max. energy per second = 5000/3600 = 1.3888 kWh
Max. energy per second
Example
1.3888 kWh
2, Calculate Max. pulses per second from
Example
Pulse width = 50 ms
Max. Pulses per second = 500 /
Max. Pulse per second = 500 /

Alarm output

An Alarm Output generates an alert when a predetermined value is exceeded or receded for Volume, Flow, Energy or Power, or
when Signal is lost or gained. When an alarm is activated a message is generated on the status line and the corresponding output
alarm symbol will flash.
