Edwards GXS 160/1750 - Connect to the Emergency Stop Circuit; Connect and Set up the Cooling Water

Figure: The controls/connectors on the rear of the pump (system with rear exhaust
and castors/levelling feet ed), item 19.
3.8 Connect to the emergency stop circuit
Note:
If not connecng to own control equipment, the external EMS link plug supplied to the
EMS connecon on the rear of the dry pumping system must be ed. Failure to do so
will result in not being able to operate the dry pumping system. Refer to (Figure: The
controls/connectors on the rear of the pump (system with rear exhaust and castors/
levelling feet ed), item 22).
If required, customer's control equipment can be connected to the dry pumping system
to shut it down in an emergency using the EMS connecon. The emergency stop control
must be compliant with IEC 60947-5-1. This should be a red self‑latching mushroom
push buon on a yellow background. Refer to (Figure: The controls/connectors on the
rear of the pump (system with rear exhaust and castors/levelling feet ed), item 22).
3.9 Connect and set up the cooling water
WARNING:
Do not turn on the cooling water supply unl the compleon of the electrical
installaon of the dry pumping system or condensaon may form inside the
enclosure and there may be a risk of electric shock.
CAUTION:
Remove both the outer dust caps and inner plasc plugs from the water inlet and
outlet ngs before connecng the cooling water hoses.
CAUTION:
Do not apply excessive torque to the water ngs when connecng the water supply
to the dry pumping system as this may cause damage to the manifold. Use a suitable
spanner to prevent the bulkhead ngs on the dry pumping system from turning
while ghtening up the connectors.
CAUTION:
Fit the inlet strainer (supplied Y strainer) into the supply side of the cooling water
system to prevent damage to the cooling system within the dry pumping system.
Notes:
1. For opmum water cooling, ensure that the cooling water supply meets the
specicaon given in Cooling-water data on page 25. Ensure that the water supplies are
connected in parallel. Refer to Figure: The controls/connectors on the rear of the pump
(system with rear exhaust and castors/levelling feet ed), items 17 and 13.
