3.4 As per IS: 2429 the following sizes of chains can be used upto the weight as mentioned in the
below chart.
4. OPERATION:
4.1 Prior to commissioning of the pump, check the following.
FILL THE OIL INSIDE THE MECHANICAL SEAL HOUSING WITH PROPER GRADE REFER CHART IN
7.5 OF CLEAN OIL FREE FROM MOISTURE. ENSURE THE MECHANICAL SEAL HOUSING OF THE
PUMP IS DULY FILLED AS PER CHART IN 7.6. CHECK THE OIL PLUG OF THE MECHANICAL SEAL
HOUSING IS INTACT.
4.1.1 Check the insulation resistance of winding by using 500 V megger. The insulation resistance of
winding should not be less than 10 mega-ohms for motor rating upto 45kW and 50 mega-ohms
beyond 45kW at phase to phase and phase to Earth. This test should be carried out at free end of
the cable. If the insulation resistance is found less than mentioned above then please consult our
service personnel.
For continuity test, connect the two wires of megger between the two ends of the same phase of
motor. It should show zero resistance. This test should be carried out for the phases.
The resistance across two moisture sensing wires M1 and M2 should be above 5 MΩ. Make sure
to remove control cable connections from terminal board [M1 and M2] before testing this. If the
resistance found less, please consult our service department. The megger test for phase to phase
and phase to Earth should be conducted serially. The megger test should show insulation
resistance above 10 MΩ for motor rating upto 45kW and 50 MΩ beyond 45kW .
4.1.2 The control panel is provided with auto/manual switch. When the switch is on "Manual" position the
pumpset can be started manually by the start push button provided the liquid level is above the low
level electrode. If the switch is on "Auto" position it will start automatically if liquid level in the sump,
is above the high-level electrode. The pump set gets switched off automatically for any position of
Auto Manual switch if liquid level goes down just below the low-level electrode. This is indicated by
glowing of red lamp on control panel.
When the pumped liquid gets mixed up with the oil in the casing cover, it is indicated by glowing of
red lamp under name plate contamination. After rectification of the fault, resetting switch is to be
pressed first and then the pump set will get started by pressing "Starting switch" if it is operated on
"Manual position" or automatically if control panel is operating on "Auto position".
Before change over from star to delta connection, time delay should be sufficient to allow the motor
to attain its normal running speed. The same depends upon the load of the motor and it is generally
around 10 second.
4.1.3 LIQUID LEVEL CONTROLLERS ARE INCORPORATED IN THE PANEL TO PROTECT THE
PUMP FROM DRY RUNNING. THE LOW-LEVEL ELECTRODE SHOULD BE POSITIONED IN
SUCH A MANNER THAT LOWEST END OF ELECTRODE REMAINS ABOVE MOTOR BODY. IF
LOW LEVEL ELECTRODE IS NOT INSTALLED PROPERLY THE MOTOR BODY IS LIKELY TO
BE HEATED UP AS COOLING OF MOTOR IS DONE BY LIQUID IN THE SUMP AROUND THE
STATOR HOUSING. HENCE SUBMERGENCE UPTO FULL CORE LENGTH OF MOTOR IS
REQUIRED.
4.1.4 Before starting the pump, check the direction of rotation is as outlined below.
