Programming31 Rev. B 06/2011 CM8.4 Device Control8.4.1 Output for target temperatureThe output can provide a predefined value of full analog range when signaloutput is 0 … 5 V.?XO Request for the output modeO=25 output of a constant voltage at 1.25 V (25% of 0 … 5 V)O=255 switches back to the temperature controlled output8.4.2 Analog output, scalingAccording to the temperature range of the model, it is possible to set themaximum voltage value according to a temperature value (e.g., the maximumvoltage 5 V shall represent 200°C). The same setting is possible for theminimum value.H=500 the maximum voltage value is set to 500°CL=0 the minimum voltage value is set to 0°CYou cannot set these values for thermocouple output. The mini-mum span between the maximum / minimum settings is 20 K.8.4.3 Alarm outputThe alarm output can be set to N.C. (relay contacts are closed while in homeposition) or N.O. (relay contacts are open while in home position). The alarmoutput can be activated by:Internal sensing head temperatureTarget temperatureK=0 alarm output disabledK=4 Sensor head ambient temperature lower than threshold, relayN.O.K= 2, XS=125.3 Target temperature lower than threshold, relay N.O.,threshold setting to 125.3℃(if U=C is set)
