1 Use and brief description Temperature relay to protect transformers against excess temperature and to control a fan. The temperatures in the windings are monitored with three Pt 100 sensors. The core temperature can be monitored with a fourth sensor. The 4 alarms/output relays are used to control the fan, to signal an advance warning and to switch-off the transformer. Various programs facilitate using the alarm ideally for each application. Depending on the program, e.g.
Program 1: 3 sensors in the windings: Fan/FAN (with cyclic test) Advance warning 8alr8 Shutdown 8trp8 Malfunction (sensor error) Program 3: 3 sensors in the windings and 1 sensor in the transformer core: Fan/FAN (with cyclic test) Advance warning (winding) / malfunction combined 8alr8 Shutdown (winding) 8trp8 Shutdown (core) 8Cor8 Alarm 2 simultaneously to reach the advance warning temperature and the fault message.

5 Important information WARNING Hazardous electrical voltage! Can lead to electric shock and burns. Before starting work, switch plant and device voltage-free. The flawless and safe operation of a device requires that it is shipped and stored appropriately, professionally installed and put into operation and operated according to its intended use.
6 Programs 4 programs (Pr) can be selected in the factory version. Starting from these programs, it is especially simple to adapt the device to the application. First select the program that fits your application and then change the individual parameters! All parameters are reset with when switching the program to "factory settings" (see "Connection Diagram" and see "Factor Settings").
