THE TEMPERATURE CONTROLLER
2 of 17
ABOUT THE ATC™
The Automatic Temperature Controller (ATC) can be
manually programmed to reach a desired temperature or
computer controlled for sophisticated temperature
profiling. The controller automatically determines the best
settings for optimal heating based on the thermal
response of a particular system. It features two
thermocouple inputs and one 24V heater output, allowing
regular or cascade operation. Regular or single loop
control is used for accessories with only a sample
thermocouple. Accessories equipped with a sample and
heater thermocouple use cascade or double loop control.
Cascade control minimizes damage to system
components, allows for over sizing heaters for optimal
heat-up rates and extends heater life by reducing thermal
cycling of the heater.
This manual contains only “quick start” instructions. For
detailed instructions see the included Watlow manuals.
ENVIRONMENTAL
CONDITIONS The Automatic Temperature Controller (ATC) is intended
for use in light industrial and laboratory environments.
GETTING READY Familiarize yourself with the temperature controller by
referring to Figures 1, 2 and 3.

CONNECTING THE ATC To connect the temperature controller to the accessory:
•Check to make sure that all the switches on the
temperature controller are off (Figure 1).
•Plug in the AC line cord into the unit and into a
suitable AC outlet (Figure 2).
•If your accessory has only one thermocouple,
connect the thermocouple to the connector
labeled TC1 on the back of the temperature
controller.
•If your accessory has two thermocouples,
connect the heater thermocouple to the
connector labeled TC2 on the back of the
temperature controller and the sample
thermocouple to TC1.
•Connect the heater to the heater connector
located on the front of the temperature controller.

SETTING THE HIGH
POWER LIMIT For routine operation, the high power limit should be set to
an initial value of 75% for heating to temperatures above
200ºC or to 35% for temperatures up to 200ºC.
•Simultaneously press both the Up-arrow Sand

Notes For operation of the HVC-DRP-4 and HVC-VUV-4 diffuse
reflection reaction chambers at or near their high
temperature limit, set the high power limit to 92.
The high power limit controls the percentage of full power
that is sent out to the heaters. The optimum setting
depends on the set point temperature and on the heated
device. If this high power limit is set too high and the set
point is close to the high temperature limit of the heated
device, the heater(s) may heat too quickly and burn out. If
the high power limit is set too low, the heated device may
heat too slowly and may not reach the set point. Adjust
this setting as needed from the recommended initial
settings to achieve the desired heating profile.

TROUBLE SHOOTING If the front panel fails to light up:
•Check if the power outlet fuses are blown (see
Table 2 for the replacement fuses).
If the ATC fails to heat your device:
•Check if the fuses are blown (see Tables 1 and 2
for a list of replacement fuses).
•Check if the heaters are still operational by
measuring their resistance with an ohmmeter,
To measure the resistance of the heaters:
•Disconnect the heated accessory from the
temperature controller.
•Connect an ohmmeter across the two pins on the
heater connector as indicated in Figure 4.
•Heater failure is indicated by an open circuit or a
short. An undamaged heater will measure a few
ohms, as indicated in Table 3.
