Edwards iXM Series User Manual

4.6.8 Connect to the emergency stop circuit
The EMS (con
trolled stop) buon on the front panel of the system is used to stop the
pump in an emergency.
Note:
The EMS buon (Figure: Fron
t panel controls, item 1) when used on its own does not
isolate the electrical supply to the system and does not give an EMO (Emergency O)
funcon.
Note:
All ref
erences in this manual to the EMS buon and/or to the EMS abbreviaon, do not
describe a rated controlled stop circuit. The EMS buon is used as a controlled stop
buon in all our products. The same reason applies to the EMS link plug.
The system has an external emergency stop circuit that can be connected into the
control equipment.Refer to Figure: Controls/connectors on the rear of the system and
Table: Electrical connecons. In this case, the controlled stop control should be
compliant with IEC 60947-5-5, a red self-latching push buon on a yellow background.
If you operate the pumping system without connecon to the control equipment, install
the external EMS link plug (supplied) to the EMS connecon on the rear of the pumping
system (Figure: Controls/connectors on the rear of the system). If the EMS link plug is not
installed the system will not operate.
Emergency o (EMO) funconality
If EMO funconality is necessary (for example, for the requirements of SEMI S2), install
the pumping system in combinaon with an our disconnect box.
The disconnect box is available as an accessory. Refer to Accessories on page 93. Refer to
the disconnect box manual for installaon instrucons and informaon about how the
pumping system can be shut down in an emergency. The photohelic switch/gauge
(available as an accessory) monitors the loss of extracon from the enclosure, which
agrees with SEMI S2 requirements.
For pumps that are installed into an integrated system and receive their power from that
system, an emergency o can be achieved by the connecon of the controlled stop
circuit on the pump into the integrated system's emergency o circuit.
Refer to Controlled stop on page 63 for more informaon about pump behaviour aer a
controlled stop.
4.6.9 Connect the cooling water supply
WARNING: ELECTRICAL HAZARD
Risk of injury and damag
e to the equipment. Do not turn on the cooling water supply
unl the electrical installaon of the pump is complete. Failure to do so can cause
condensaon in the enclosure and a risk of electric shock.
