Page 4: Short Description
DAG-A1T 5. Short description The panel instrument DAG-A1T is a 4-digit device for temperature metering via thermocouple and a visual limit value monitoring via the display. The configuration happens via three front keys. An integrated programming interlock prevents unrequested changes of the parameter and can be unlocked again via an individual code. -
Page 5: Electrical Connection
DAG-A1T 7. Electrical Connection Type DAG-A1T3000R with a supply of 24 VDC Advice: The galvanic insulation in devices with temperature sensors that do not have a galvanic connection to an extrinsic potential, can be cancelled by a bridge from terminal 3 to 4 and thus stabilise the device against external failures. -

Page 7: Setting Up The Device
DAG-A1T 9. Setting up the device 9.1 Switching on Once the installation is complete, you can start the device by applying the current loop. Check beforehand once again that all the electrical connections are correct. Starting sequence For 1 second during the switching-on process, the segment test (8 8 8 8 8) is displayed, followed by an indication of the software type and, after that, also for 1 second, the software version. -

Page 11: Reset To Default Values
DAG-A1T 10. Reset to default values To return the unit to a defined basic state, a reset can be carried out to the default values. The following procedure should be used: Switch off the power supply Press button [P] Switch on voltage supply and press [P]-button until „- - - -“ is shown in the display. -

Page 16: Safety Advice
• endanger human life and/or can destroy the equipment. The terminal area of the devices is part of the service. Here electrostatic • discharge needs to be avoided. Attention! High voltages can cause dangerous body currents. page 16 DAG-A1T K05/0722... - Page 17 DAG-A1T Galvanic isolated potentials within one complex need to be placed on an • appropriate point (normally earth or machines ground). So, a lower disturbance sensibility against impacted energy can be reached and dangerous potentials, that can occur on long lines or due to faulty wiring, can be avoided.

Page 18: Error Elimination
• Please check the possibility to set aside the galvanic isolation for a discharging of failures as described under chapter 7 „Electrical connection“. Before make sure that the possible metal sensor is separated from the sensor element. page 18 DAG-A1T K05/0722... -
