MOUNTING
All ovens are supplied with slide mounting brackets.
Before moving the oven, make
sure the locking pins are engaged to prevent the slides from moving.
The oven should only be moved via an overhead crane or fork truck using the supplied
eyebolts on the top of the oven. Position the oven between the slide mounting brackets
and align the front two holes in the slide assembly over the tapped holes in the test
frame.
CAUTION: Do not block the perforated areas on the rear cover. Cooling is required for
the electronics and the blower motor.
ELECTRICAL WIRING CONNECTIONS
The control system has been connected to the chamber before shipment. A conduit
feed through has been provided on the lower feed through panel to allow the wiring to
remain in place when removing the rear cover. The feed through panel can be removed
if necessary. Any conduit provided shall be permanently secured / mounted during
installation. Please make sure that any additional wiring meets all local electrical codes.
NOTE: The control system is supplied with a power cord and plug. Refer to the Oven-
Test Chamber Specifications page for a description of the cord and plug. Ovens shipping
to Europe will also include a matching IEC receptacle.
NOTE: The oven door has a safety interlock switch. The door must be closed for the
oven to operate. This feature was designed to protect the operator from hot or cold air
blowing directly on them while accessing the oven.
THERMOCOUPLE
The thermocouple measures the voltage that is generated as the temperature increases.
A current will flow providing an input signal for the control system to monitor and provide
operational control.
The tip of the thermocouple must be in the heated chamber and not covered or shielded
to the point where it cannot sense the actual temperature.
If the temperature controller displays the message "S.br" (sensor break), the
thermocouple circuit is faulty. A loose connection, broken wire or burned out
thermocouple could be the
cause.
When replacing thermocouples, remember to use the same type thermocouple.
Extension wires and connectors must also be compatible with the thermocouple and
controller. Be sure to observe correct polarity of thermocouple extension wire. Red leg
is always negative for thermocouples.
NOTE: The thermocouple has not been calibrated unless specifically ordered as such.
Upon request, calibration will be preformed on the thermocouple and a calibration report
will be enclosed in the appendix.
