OPERATION
3.2.1
HI / LO Power Selection
Prior to turning on the unit, select the HI (80 watt) or LO (25 watt)
power setting for each stage.
3.2.2
Power ON/OFF
Before connecting AC power to the Model 1015, verify rear panel
line voltage selector corresponds to the available power line
voltage. Verify correct fuse installation.
Immediately after power ON, the Model 1015 enters the STOP
condition: STOP annunciator on, all others off. In the STOP
condition, the unit applies no power to the heaters.
3.2.3
SINGLE Cycle Operation
In
SINGLE
cycle operation, the Model 1015 warms the first and
second stages to room temperature. Upon reaching room
temperature, the Model 1015 shuts off heater output to that stage
and does not allow it to go back on.
To select the
SINGLE
cycle operation, switch the rear panel
CONT
switch to the down position. To initiate the warm-up cycle, press
the front panel
START
button. The
START
LED lights and the unit
monitors the First and Second stage sensor inputs to determine if
they are already at room temperature. If they are, the stage enters
the
READY
state. If not, the unit turns on the power to the stage
and indicates it by lighting the red
POWER
LED.
If the
POWER
LED does not light and the stage is not
READY
,
there is a fault in either the sensor or heater connections. The unit
applies power to the stages until they are both at room
temperature, or
READY
. Terminate the warm-up cycle at any point
by pressing the
STOP
button. The
STOP
button returns the unit to
the power-up state.
