Important: Power Factor leading is represented as an unsigned value.
Power Factor lagging is represented as a negative value. The kWH and
kVARH values represent TOTAL values (sum of import and export). The
kWH REVERSE value represents kW exported.
The STATUS screen (Figure 5.9) displays and monitors the present state of
the three Powermonitor control relays, four status inputs, and any of
setpoints or alarms that are in an active condition. A description of the data
shown on the STATUS screen is given below.
Figure 5.9
Status Screen
Relay
This portion of the STATUS screen shows the present condition of the three
relays.
1. OFF. A relay is considered to be OFF when its normally–open contacts
are open (for Relay #1 this is R14/R11) and normally–closed contacts are
closed (R11/R12). This state occurs when the relay is not assigned to any
setpoint, or when the assigned setpoint is not in an active condition.
2. ON. A relay is considered to be ON when it has been activated by a
setpoint. In this state, the normally–open contacts have been closed and
the normally–closed contacts have been opened. This state occurs when
a relay has been assigned to a setpoint and the setpoint parameter value is
outside the bounds of its low or high limits.
