4 Sensors Pt100 (RTD), Monitoring of Core, Panel-Mount
Monitoring Programs: 3 sensors in windings: Alarms/outputs for: Fan (with cyclic test) Alarm Trip Sensor-Error 3 sensors in windings and 1 sensor in core: Alarms/outputs for: Fan (with cyclic test) Alarm (winding and core) Trip (winding and core) Sensor-Error For core and winding different limits can be program - med. 3 sensors in windings and 1 sensor in core: Alarms/outputs for: Fan (with cyclic test) Alarm (winding) / sensor-error (combined) Trip (winding) Trip (core) Alarm 2 reports sensor-error and alarm 3 sensors in windings and 1 sensor in core: Alarms/outputs for: Trip (core) Alarm (winding) Trip (winding) Sensor-Error The relay for error (short-circuit or break of sensor- lines) is preset in closed-current mode (alarm also at loss of supply-voltage or failure in the device = moni- toring of function of the device). All other relays are in operating-current mode (pick up at an alarm = no alarm when switching on and off supply-voltage). The mode of the relays can be changed by the user. Temperature-Relay for the protection of transformers from over-temperature and for controlling a fan. Monitoring of the temperatures in the windings is made with 3 sensors. The input for the 4th sensor can be used for moni- toring the temperature in the core or for a sensor for ambient temperature. The 4 alarms/relay-outputs control the fan and release signals for alarm and trip if limits are exceeded. Dif- ferent programs allow to adapt the required alarms to the application. Depending on the program e.g. extra alarms for sensor-error or for tripping because of over- temperature in the core are available. Other applications: The forth sensor can be used to monitor the room, in which the transformer is set up and the alarm can control a forced cooling of the room. The TR440 can also be used for the monitoring of temperatures e.g. at motors. Pt 100-Temperature Relays Type TR 2015-03-30 2017-09-06 TR440 Part numbers: T224184 T224185 RS485
