INM MTL 130-0175 Rev 453.3 Electronic unit connectionsThe following points should be observed for the wiring between the sensor/reactor unit and thecontrol/display electronics.• The cables should avoid as much as possible tracking other high current cables.• The signal outputs may be connected using standard instruments cable (e.g. 7/0.2). Allsignal outputs are short/open circuit proof.• If the cables are extended only use wire of similar type and current carrying capacity.The thermocouple wire pairs 3&5 and 14&16 must use Type K thermocouple extensionor compensating cable.WARNINGIt is strongly recommended that the Temperature Error volt-free contacts(terminals 10 and 11) are used to activate a sample cut-off in the event thatexcessive sample flow (greater than 250ml/min) causes the catalyst to overheat. Typically the contacts would be used as a logic input to the overallburner controller. The controller would apply a delay to the burner shut-offcommand so as to avoid shutting the burner down in a transient temperatureerror situation.120-0645/1A.C. + -13 14 15 16A.C. + + NC+ - - -1 2 3 4 5 6 7 8 9 10 11 12Fuse Type ‘T’ 1.6A20mm x 5mmØF US E230Set A.C. supply voltageherebeforeapplying power to(Re-wirable plugsupplied)ACMains ConnectorVia cable glands in enclosureSensor HeaterSensor T/CUse Type K Comp cableSensor SignalAnalogue O/PTemperature Error(Closed = OK)Catalyst HeaterCatalyst T/CUse Type KComp cableVoltage SelectorEnsure this is correctBEFORE powering |
