Float Switch And Panel Chart - ITT Goulds Pumps 3885 Instrucciones De Instalación, Funcionamiento Y Mantenimiento

Use the pump H-O-A (Hand-Off-Automatic) switches in
Hand to test the pumps. If they operate well in Hand
proceed to test Automatic operation. If the pumps run
but fail to pump, they are probably air locked, drill the
relief holes per the instructions in the Piping Section.
Place Control Panel switch(es) in Automatic position
and thoroughly test the operation of the ON, OFF, and
Alarm floats by filling the wetwell with clear water.
Important: Failure to provide a Neutral from the power
supply to a 1Ø, 30 volt Control Panel will not allow the
panel control circuit to operate. The Neutral is necessary
to complete the 115 volt control circuit.
Check voltage and amperage and record the data on the
front of this manual for future reference. Compare the
amperage readings to the pump nameplate maximum
amperage. If higher than nameplate amperage investigate

FLOAT SWITCH AND PANEL CHART

The purpose of this chart is to show the required switch
quantities and the function of each switch in a typical
wastewater system. The quantities required vary de-
pending on the switch type, single-action or wide-angle.
Switch quantities also vary by panel type: simplex with
and without alarms, and duplex with alarms.

cause. Operating the pump off the curve, i.e. with too
little head or with high or low voltage will increase am-
perage. The motor will operate properly with voltage not
more than 10% above or below pump nameplate ratings.
Performance within this range will not necessarily be the
same as the published performance at the exact rated
nameplate frequency and voltage. Correct the problem
before proceeding. Three phase unbalance is also a pos-
sible cause. See Three Phase Power Unbalance and follow
the instructions.
Reset the Alarm circuit, place pump switch(es) in the
Automatic position and Control Switch in ON position.
The system is now ready for automatic operation.
Explain the operation of the pumps, controls and alarms
to the end user. Leave the paperwork with the owner or
at the control panel if in a dry, secure location.
