Q-SERIES DI HEATER OPERATION / MAINTENANCE MANUAL
2.1.c Caution
A Caution message indicates a potentially hazardous situation, which, if
not avoided, could result in minor or moderate injury. It may also be used
to alert against unsafe practices. Following is a typical example of a
Caution
message as it could appear:
Caution
Hot Surface
Do not touch. Can cause
skin burns upon contact.
Disconnect and lockout
power and allow surface to
cool before servicing.
2.2 EMERGENCY OFF (EMO)
The EMERGENCY OFF button (EMO) is located on the front of the
heater. When the EMO circuit is activated by pushing the button in, the
equipment will be placed into a safe shutdown condition. The EMO will
de-energize the heaters and process interlock devices. Other devices on
the electrical panel remain energized
and hazardous voltages will be
present at the power supply and power supply fuses, sub-panel circuit
breakers and contactors. Use the Main Power Disconnect Switch to
remove power altogether.
Figure 2-1
After the EMO button is disengaged, the heater must be reset by
pressing the blue RESET button located on the front of the heater near
the EMO button to reactivate the controls.
