25-81 Pump Status
Option: Function:
[X] Disabled
[O] Off
[D] Running on Frequen-
cy Converter
[R] Running on Mains Pump Status shows the status for the number of pumps selected
in
Number of Pumps , par. 25-01. It is a readout of the status
for each of the pumps showing a string, which consists of pump
number and the current status of the pump.
Example: Readout is with the abbreviation like “1:D 2:O” This
means that pump 1 is running and speed controlled by the fre-
quency converter and pump 2 is stopped.
Disabled (X): The pump is interlocked either via Pump Inter-
lock
, par. 25-19, or signal on a digital input programmed for
Pump (number on pump) Interlock in
Digital Inputs , par. 5-1*.
Can only refer to fixed speed pumps.
Off (O): Stopped by the cascade controller (but not interlocked).
Running on Frequency Converter (D): Variable speed pump, re-
gardless if connected directly or controlled via relay in the
frequency converter.
Running on Mains (R): Running on mains. Fixed speed pump
running.
25-82 Lead Pump
Option: Function:
0 N/A Readout parameter for the actual variable speed pump in the
system. The Lead Pump parameter is updated to reflect the
current variable speed pump in the system when an alternation
takes place. If no lead pump is selected (Cascade Controller
disabled or all pumps interlocked) the display will show NONE.
25-83 Relay Status
Array [2]
On
Off Read out of the status for each of the relays assigned to control
the pumps. Every element in the array represents a relay. If a
relay is activated, the corresponding element is set to “On”. If
a relay is deactivated, the corresponding element is set to “Off”.
