Prior to any operation of this unit, it is highly recommended that the operator read completely
through and understands the Basic Safety Precautions on pages 7-8 of this manual. After
understanding these items, the procedure below details the basic operation of the unit.
Basic operation of the unit consists of verifying that all safety conditions are met, and then setting
the operational parameters. Once these two steps are complete, the unit should provide process
fluid at the required temperature, and run with no normal user intervention.
Ensuring that safety conditions are met prior to initial unit power-on consists of checking that fluid
is actually flowing to the unit, and verifying that all minimum safety requirements are met. Once
this has been established, the unit can be powered on for the first time. Once all the conditions
are met, and the unit is powered on, it will return a low flow condition and a high limit failure by
default. Press the "Low Flow Reset" button for three seconds. The unit will check for an adequate
flow condition, and if one exists it will begin to bring the temperature to the set point. Then the
"Hi-Limit Reset" button should be depressed, in a fashion similar to the "Low Flow Reset". If the
condition is safe the unit will begin to bring the fluid temperature to setpoint. Every time the unit
is powered on, the "Low Flow Reset" and "Hi-Limit Reset" buttons will need to be depressed. The
next step then is to set the process set point to the required temperature. This is accomplished
by the following:
•
Refer to the temperature controls panel.
•
Verify that it is displaying the process temperature in the proper units. If it is not, refer to the
accompanying temperature controller manual.
•
Once the controller is displaying the proper units, the set point can be adjusted by first
momentarily pressing either the up or down key on the controller to view the current set point.
•
Momentarily pressing either the up or down key on the controller will then change which
numerical position is to be adjusted. The flashing digit is the highlighted digit.
•
Pressing and then holding either the up arrow key, or the down arrow key will either increment
or decrement the highlighted value.
•
By momentarily pressing the up or down key on the controller, you can select the next value
of the temperature you wish to adjust. Repeat the procedure in step five to adjust the next
value of the temperature you have selected.
•
After approximately 10 seconds of user inactivity, the controller will return to operation, and
will try to control the temperature to the current set point.
•
The first time the unit is powered up, it is also recommended that the Auto Tune procedure be
run. Once the set point has been adjusted to normal operating conditions, the Auto Tune
procedure can be run. To start the Auto Tune procedure, press and hold the up arrow and
down arrow keys simultaneously for 3.2 seconds, then release. The display will begin
flashing, and will continue to flash throughout the Auto Tune process. For more details of the
Auto Tune process, refer to the accompanying controller manual.
•
You will not need to run the Auto Tune procedure again unless you significantly change the
value of the set point, or if system stability is unacceptable.
