The Operator Panel push-buttons & indicators
Illuminated "E-Stop" Push-button (Latching, Red)
Red indicator lamp illuminates Red LED whenever the E-Stop push-button is activated (depressed).
Since the E-Stop push-button is a latching push-twist/pull type, it maintains either an active (depressed)
or inactive (pulled out) state, and once it is manually activated it must then be manually twisted and
pulled back out before Control Power can be restored. When the E-Stop is not activated, it provides
normally-closed contacts in the 24Vdc safety interlock circuit to the safety relay. Pressing the E-Stop
opens the safety circuit which then removes 240Vac Control Power from the socket and the meter.
Resetting the safety circuit, however, does not automatically re-enable the control power (see below).
Illuminated "Reset" Push-button (Momentary, Blue, then Red when power is enabled)
Blue indicator lamp illuminates the Red LED whenever Control Power is ON. The "Reset" push-button is
of a momentary type and provides normally-open contacts in the 24Vdc Reset circuit to the safety relay.
When pressed, the safety relay is reset (so long as there is no other safety interlock circuit violation)
and thereby enables the system. If the control power is not reset, the unit will not be able to power the
meter or perform any tests.
