B-4.4) Moisture Sensors:
A normally open (N/O) detector is installed in the pump
seal chamber, which will detect any moisture present,
and a continuity test resistor built into the motor. The
test resistor is rated 1 watt at 330K ohms. The moisture
sensors MUST be connected to moisture detector
control in the control panel which includes a continuity
test circuit, see Figure 4 for typical wiring diagram. The
normally closed (N/C) contact of the moisture detector
MUST be connected in series with the stop button of the
pilot circuit of the magnetic motor controller. Wiring must
be provided from the moisture detector sensor probe
leads of the motor designated W1 and W2 to terminals 9
and 10 of the 2800-XXX control. Terminal pair 1-2 must
be continuously energized from an A-C supply line of
electrical characteristics shown on the data table. In the
event of moisture detection, the pump should be pulled
and the source of the failure located and repaired. IF
MOISTURE DETECTION HAS OCCURRED, SCHEDULE
MAINTENANCE AS SOON AS POSSIBLE !
B-4.5) Control Panel and Electrical System:
The control panel and the electrical system MUST be
properly designed and wired to include at least, but not
limited to the following;
a. Proper grounding per NEC.
b. A temperature sensing circuit (see Fig. 4)
c. A moisture detection circuit with continuity test
circuit (see Figure 5)
d. A level control system.
e. A main power manual disconnect and lock out.
f. A motor starter and overload system.
B-5) When Used with a Variable Speed Drive:
Maximum turndown should not exceed 2:1. Drive should be
set to operate in constant torque mode.
It is advisable that all three phase control panels be
purchased from the factory.
If a panel is to be supplied locally, it is recommended that
the Crane Pumps & Systems Pump Monitor Relay (P/N
134667) be used to perform the control circuit functions for
the Temperature and Moisture Sensor Monitoring described
in sections B4.3 and B4.4. The Pump Monitor Relay was
designed to perform these functions in a compact module
that can be base or panel mounted and is resistant to noise
issues found with some VFD’s. Indicator lights on the front
display notify the operator in the event of a fault condition
for either temperature, moisture or both. Normally open and
normally closed contacts are flexible to accommodate nearly
any wiring scenario and the moisture sensor sensitivity can
be adjusted to prevent nuisance alarms.
SECTION: C START-UP OPERATION
C-1) Check Voltage and Phase:
Before operating pump, compare the voltage and phase
information stamped on the pump’s identification plate to the
available power.
C-2) Check Pump Rotation:
Before putting pump into service for the first time, the motor
rotation must be checked. Improper motor rotation can result
in poor pump performance and can damage the motor and/
or pump. To check the rotation, suspend the pump freely,
momentarily apply power and observe the “kickback”.
“Kickback” should always be in a counter-clockwise direction
as viewed from the top of the pump motor housing and will
always be in the opposite direction of the rotation arrows
cast in the pump volute.
C-2.1) Incorrect Rotation for Three-Phase Pumps:
In the event that the rotation is incorrect for a three-phase
installation, interchange any two power cable leads at
the control box. Recheck the “kickback” rotation again by
momentarily applying power.
C-2.2) Test Procedure For Moisture Sensor Control:
With a moisture detection control, a normally closed push
button and neon indicating lamp is typically provided as a
means of checking the moisture sensing components. When
the push button is depressed, the indicating lamp will be
illuminated to indicate (A) power is supplied to the control,
(B) the control is operative, and (C) wiring to the moisture
sensing probes in the motor is intact. This procedure should
be performed periodically to confirm integrity of the circuit.
C-3) Start-Up Report:
Included at the end of this manual is one start-up report
sheet, this sheet is to be completed as applicable. Return
a copy to Barnes and store the second in the control panel
or with the pump manual. It is important to record this data
at initial start-up since it will be useful to refer to should
servicing the pump be required in the future.
C-3.1) Identification Plate:
Record the numbers from the pump’s identification plate on
the START-UP REPORT provided at the end of the manual
for future reference.
