3.3 Function display via light-emitting diodes
LED – red = High water alarm, error P1 or P2
LED - solid yellow = Pump is in operation
LED - blinking yellow = Pump is running via the overrun
function
LED - solid green = Automatic mode
LED - blinking green = Manual mode
LED - irregular green blinking = Manual mode shut off after 2 min.
3.4 Display
Automatic switching off of the background lighting:
If no further settings are actuated on the device, the background lighting switches off automatically after 2
minutes. As soon as the rotary switch or one of the push-buttons is activated,
the background lighting switches
back on again.
The top line always shows the level. The bottom line shows the operating hours when the pumps are not
triggered. If any errors arise, then they will be displayed alternatingly on the display's bottom line:
P1 :Therm. fault 1 (Terminal 01 / 02 bi-metal contact opened)
P1 :Therm. fault 2 (Terminal 02 / 03 bi-metal contact opened)
P2 :Therm. fault 1 (Terminal 06 / 07 bi-metal contact opened)
P2 :Therm. fault 2 (Terminal 07 / 08 bi-metal contact opened)
P1: or P2: Over-current (the respective motor circuit breaker has triggered)
Depending on how the PS2 SYSTEM's inputs are configured, further error reports, e.g. high water
float, residual current circuit breaker, DI error or rotary field error will appear (connection assignment
is laid out in the wiring diagram).
High water alarm the level has transgressed the high water setting
Switch-on point under- the settings for the pump turning on and off
switch-off point overlap
High water under- the setting for the high water alarm is under the
switch-on point switch-on point
Switch points after the measuring range for the 4 - 20 mA probe has been changed
check at least one switch point is outside the measuring range.
