The Programmable Temperature Controller will stop control and will stay in this state until the
problem is corrected. The only way to correct this error is to power-down (turn off) the Program-
mable Temperature Controller and then turn it back on.

VII.3 High/Low Temperature Limit Error

If a temperature outside of the Programmable Temperature Controllers high or low temperature
limits is detected, either of the two messages

-lÏ-

-h1-

hown directly above will be displayed.

The Programmable Temperature Controller will stop control and will stay in this state until the
problem is corrected. Once corrected, the unit will return to viewing the controlled temperature.

VIII. TROUBLESHOOTING

In the event that the Programmable Temperature Controller does not appear to be working, check the
power fuses (located in a removable section of the power input block) to determine whether they are
still functional.

Note:

Disconnect the Programmable Temperature Controller from the power source
(mains) before checking the fuses.

The power fuse protects the controller electronics. This fuse (Brookfield Engineering Laboratories
part number HT-98H) is a 3A/ 250V fast blow Littlefuse type 3AG 312.003 or equivalent.

The Programmable Temperature Controller is designed to require a minimum amount of user main-
tenance. There are no user serviceable parts inside the unit. In the event of difficulties with the prod-
uct, contact Brookfield Engineering Laboratories or its authorized representative. When calling
Brookfield Engineering Laboratories, please have the serial number of the unit available (the serial
number is indicated on a label on the bottom of the controller).
