Tests
Tests should be performed carefully and regularly.
The safety of personnel as well as the condition of
equipment may depend upon the proper operation of
any one of the functions of these controls. Test the
CONTROL instrument every 40 hours. Check that
the CONTROL instrument OUT LED is cycling on and
off. Also, verify that the heater is working.
Test the HI-LIMIT instrument every 40 hours.
With the oven operating at a given
temperature, set the HI-LIMIT down to the
setpoint operating temperature. The HI-LIMIT
instrument has tripped when OP1 is lit. Push
after adjusting the
HI-LIMIT instrument back to a higher setting,
or letting the oven temperature drop a few degrees based on the hysteresis value
of the HI-LIMIT.
