PEM L104-100 CONTROL PANEL WITH TRANSFORMER
PEM L104 - 100 CONTROL when connected to a suitable PEM L104 Series Sensor
will provide a dual stage waterlevel control
system. This control will operate a solenoid fill valve to maintain a constant
operational waterlevel in a fountain pond and in
addition it has a low level safety shut off for the electrical equipment in
a fountain pond, should the waterlevel drop below normal
operating depth. PEM L104 - 100 has a 24V-50VA safety power supply included
for the direct operation of a 24V solenoid
fill valve in the water make up circuit. Indicating lights provide immediate
status display. Green light is for Power 'ON', Yellow light
indicates water make up circuit is engaged. Red light indicates that the low
level safety shut off circuit is engaged and will not
disengage until normal operating waterlevel is re-established. This control
has a safety transformer for the sensor float switches,
providing 12 VDC . Time delayed 'ON' action of the water make up as of the safety
shut off prevents rapid cycling due to wave
action in a fountain pond. The wall mounted control panel is within a NEMA Type
4 corrosion resistant polycarbonate enclosure.
Wiring to sensor assembly requires 4 unshielded #18 AWG size conductors. The
installation must conform to all applicable
electrical codes.
