Starting the Thermolator
Before starting the Thermolator, verify that the system has been installed correctly for your
application.
See the Installation section
.
1
Turn on the water supply to the Thermolator. The supply pressure must be at least
25 psi for most units. Refer to the appendix G for more information on 48 kw and 300°
F {149° C} units
. Check for leaks in the cooling water and process fluid lines before
continuing.
2
Turn on main power to the Thermolator.
• The controller display and “Control Power” LED will illuminate to indicate the
control has power.
• The controller will show the firmware version on the lower display while show-
ing “
tcp ” on the upper display. After a few seconds, process temperature will be
displayed (red, bottom display) and setpoint will be shown (green, top display).
3
Set the temperature setpoint to 40° F (4.4° C)
if the Thermolator’s process lines
were recently reconfigured, or if you suspect excessive air is in the process lines.
Press to increase or to decrease the temperature setting. This will provide
additional flushing and de-aeration in the process lines via the cooling valve.
4
Press RUN .
The unit initiates a 30-second (or as otherwise defined by user parameter) venting
sequence. The Venting LED illuminates.
• The pump starts after the venting cycle is over. The Pump LED illuminates when
the pump is running.
• Normal operation begins. The heater turns on if the actual temperature is below
setpoint. The cooling valve opens if the actual temperature is above setpoint.
NOTE:
Both venting stages will be skipped if the process temperature is above the vent bypass temperature,
and the Thermolator will consequently start the pump immediately in the “RUNNING” state.
5
Set the setpoint to the desired temperature
, Shown in green on the top display.
Press to increase or to decrease the temperature setpoint. If you followed
step 3, wait until process lines are de-aerated before raising setpoints.
6
If the Alarm LED turns on, press “Silence/Reset”
to silence the optional
audible alarm.
Refer to the Troubleshooting section for more information.
NOTE: All LEDs will flash
to test their operation.
0
NOTE: If the coolant pressure
low LED illuminates, verify
that the cooling water supply
is connected properly and that
the water pressure is at least
25 PSI or greater except for 48
kw or 300
°
F {149° C} units.
Refer to the Appendix for more
information.
