List of warnings
11. Technical data
1)
The start pressure (p
start
) can be set in steps of 0.5 bar (50 kPa).
The setting is described in section 5.1 DIP switches.
2)
The stop pressure (p
stop
) is only used in systems with a pressure tank.
See section 7.3 Start/stop with 1 bar (100 kPa) differential pressure.
The technical data may be limited by the pump data. See installation and operating instructions for the pump.
Indication Warning Cause
"Warning" is permanently on. Dry running. The pump has been running without water.
"Warning" flashes once per
period.
Cycling.
The pump is cycling.
Note: Occurs only if the anti-cycling function has
been enabled. See section 8.1 Anti-cycling.
"Warning" flashes three
times per period.
Protection mode.
The pump has had too many start/stop sequences
within a short period.
Each pump start is delayed a few seconds to
protect the installation. The start delay is active
until normal operation has been re-established.
Note: The protection mode will protect the
installation when the PM Rain is set to start/stop
with 1 bar (100 kPa) differential pressure, i.e. when
DIP switch 5 is set to "ON". The protection mode
functions independently of the anti-cycling
function.
"Warning" flashes more than
three times per period.
Internal fault. Internal fault in the unit.
