Misc. Options
-ES
Emergency Shut off switch. This option key lock push button is installed
on the front panel of the master MX if ordered with the MX system. When
pushed in, the main AC contactor is opened disconnecting the AC input
power to the MX input transformer. Note that the controller (and LCD
display) will still be powered up but no power is available to the
amplifiers and there will be no output power either. The controller runs
off the LV supply, which must be turned off with the front panel breaker.
After the ES has been pushed, the provided key will be required to
release it. Once the ES button has been released, the MX
must
be
powered down using the front panel circuit breaker and turned back on
to start up again.
Note: Do not misplace the 2 keys provided, as no duplicates are
available from CI. If lost, the ES switch must be replaced. In that case,
contact AMETEK Programmable Power customer service.
