Operation 3.3 Behavior with sensor break/ measuring circuit error If a sensor break/ measuring circuit error is recognized, the process value display changes to FAIL and the Err-LED blinks. ( -> Page 11 chapter 3.5 maintenance manager/ error list). All configured alarm limts are handled as exceeded, the appropriate Outputs are switched. The OK-LED ceases and the LC Output is opened. 3.
Operation 3.5 Maintenance manager / Error list With one or several errors, the extended operating level always starts with the error list. Signalling an actual entry in the error list (alarm, error) is done by the Err LED in the display. To reach the error list press Ù twice.
Operation g g Saved alarms (Err-LED is lit) can be acknowledged and deleted with the digital input di1 or the RESET-key. Configuration, see page : ConF / LOGI / Err.r If an alarm is still valid that means the cause of the alarm is not removed so far (Err-LED blinks), then other saved alarms can not be acknowledged and deleted.
Operation 3.6.2 Alarm handling additional alarms Max. two alarms can be configured and assigned to the individual outputs. Generally, outputs OuT.1and OuT.2 can be used each for alarm signalling. Each of the 2 limit values Lim.2 and Lim.3 has 2 trigger points H.2/ H.3 (Max) and L.2 / L.3 (Min), which can be switched off individually (parameter = “OFF”). Switching difference HYS.2/ HYS.3 of each limit value is adjustable. Ü Operaing principle Src.x = 0 L.1 = OFF InL.1 * Operaing principle Src.x = 1 L.
Operation g The variable to be monitored can be selected seperately for each alarm via configuration The following variables can be monitored: w process value w control deviation xw (process value - LC limit ( LC )) 3.7 Operating structure After supply voltage switch-on, the controller starts with the operating levels. The controller status is as before power off. 126 Ù 125 3 sec.

Safety hints 10 Safety hints definition according to EN 14597 (former DIN 3440) + Modified “Temperature control devices and temperature limiters for heat generating systems” After introduction of this new standard (2005-12) the definitions described therein were changed again.
Safety hints w If the controller is connected with other units in the same signal loop, check that the equipment in the output circuit is not affected before switch-on. If necessary, suitable protective measures must be taken. w The unit may be operated only in installed condition. w Before and during operation, the temperature restrictions specified for controller operation must be met.
