APPLICATIONS
Same as 1500-D Relay above
except that additional Normally
Closed contact is provided to permit
simultaneous operation of second
pump. Extra contact can also be
used for signal purposes if desired.
Pump Up or Pump Down Control for
same applications listed above for
B/W 1500-C and 1500-D Relays. It
is also suitable for use in controlling
hydropneumatic tanks and motor-
ized valve installations.

PILOT OPERATION
CAUTION: Electrodes are terminals of live electrical circuits and must be installed
to prevent accidental contact by personnel. Control power must be disconnected before servicing.
A GOOD DEPENDABLE GROUND RETURN CONNECTION TO THE LIQUID IS REQUIRED.
Same as 1500-C Relay above
except that additional Normally
Open contact is provided to permit
simultaneous operation of second
pump. Extra contact can also be
used for signal purposes if desired. 1500-F Relay
