to manual and jog the pump by momentarily starting it before fully starting.
- Check that the direction of pump rotation is anti clockwise when viewed from
above the motor fan cover, (clockwise when viewed looking at the impeller).
If rotation is in the wrong direction correct as per section 6.6.
- Start the pump and read the current variation while opening the discharge
valve slowly. Check if the current is within the rated current of the pump with
the discharge valve fully open.
- If the current exceeds the rated current, record the voltage and current then
stop the pump. Check the system and provide the details listed below to KJI.
(See fig. 12)
- The current and voltage during operation
- Nature and viscosity of the liquid
- Piping layout and configuration (H1,H2,H3,H4. Number and type of all
bends valves tees and fittings.
- Diameter and total length of the pipe
- If the operating current is within the rated current, monitor the variation over
1 hr of continuous operation. If it remains stable stop the pumps and set the
level switch positions to complete commissioning.
6.3 Insulation Check
This section describes how to check for correct wiring and how to identify the
individual cables when the original tags have been removed during installation.
6.3.1 Insulation check of Power Cable Wiring
6.3.1.1 For both DOL and SD start ensure that the insulation resistance between
each phase and earth exceeds 10 Meg-Ohm
