Minimum pressure limiter (optional)
OFF
Minimum pressure limiter ON:
The default setting at pressure limiter has been reached
(normally closed contact has opened); pump motors 1; 2 and
valves 1; 2; 3 are switched OFF (further pressure decrease
will lead to vapour build-up in the heating installation) / check
function of valves 1; 2, check valves, check equipment and
installation for leaks (error no.: 8 is ON); Error OFF, after resolved

Temperature monitor ON:
The fixed value switch has reached or exceeded the
temperature limit; scheduled de-aeration will be turned OFF
and will be re-activated at lower temperature level (note: the
permissible constant temperature at the vessel diaphragm is
70 °C); Error OFF: self-resetting when error resolved.

SPCx-lw: current value is not reached, the temperature safety
switch of the motor has been triggered due to elevated working
temperatures, limiter has opened, (winding fault, power or
temperature overload, no motor ventilation, exception: the
power supply installation of the motor is not available or
disconnected after signal “motor ON”), may be followed by error
no.: 8 / ensure that medium and ambient temperature (module)
are within admissible ranges, if necessary supply sufficient
ventilation; check electronic installation, for recurring error »
Service; Error OFF after, when error is resolved and reset.
SPCx-hw: The default value of the motor protection switch
has been exceeded, overcurrent (winding defect, overload,
overtemperature) or an incorrect setting exists, no motor
ventilation, may be followed by error no: 8 /
ensure the permitted media and ambient
temperatures (unit), if necessary, ensure sufficient
ventilation, check the set value, and correct if necessary
(type plate pump unit: For DP units, the
value of the nominal current value is equivalent to the nominal
current × ½ for each motor circuit
switch), in case of repeated malfunction » service;
