VIII.3 High/Low Temperature Limit Error
-Lo-
-HI-
If a temperature outside of the Programmable Temperature Controller’s high or low temperature
limits is detected, either of the two messages shown directly above will be displayed. The Pro-
grammable 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.
IX. 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 (Brookeld Engineering Labora-
tories part number DVP-30) is a 2A/250V fast blow Littlefuse, fast acting type, GMA series or
equivalent.
The Programmable Temperature Controller is designed to require a minimum amount of user
maintenance. There are no user serviceable parts inside the unit. In the event of difculties with
the product, contact Brookeld Engineering Laboratories or its authorized representative. When
calling Brookeld 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).
