Installation
The unit can be installed as follows:
•
Installation in switchgear cabinet on 35 mm mounting rail according to EN 60715 for protection against
fire, external environmental conditions and mechanical effects.
•
With screws M4 for installation on walls or panel. (additional latch is not included in delivery)
•
Connection according to connection plan or type plate.
Failure to comply with the information in this instruction manual will not guarantee the function of the device.
A circuit-breaker or switch must be situated within easy reach of the
unit and fused. Installation excess current protection should be ≤ 10 A.

Commissioning
LED Power on = ready
LED Power flashes = parameter setting mode
LED 4..20 mA flashes 3 times in commissioning mode = value stored
LED 4..20 mA flashes = sensor error
LED 4..20 mA on = output 4...20 mA
7.1
Commissioning mode
(Power LED FLASHES)
Press button Zero and hold it. Switch on power supply while holding button Zero. Wait until LED power
starts blinking and release button.
Leave commissioning mode by pressing buttons Zero and Full-scale simultaneously. Commissioning mode
is finished automatically after 10 min.
Set values remain stored also when power is switched off.
7.2 Adjusting of Zero
Simulate temperature for zero at input of TMU100V with a resistor or a decade for Pt 100. Resistance see
table in this manual. Shorten terminals T2 and T3 (3-wire connection).
Press button Zero shortly.
Storing of value is confirmed by LED 4…20 mA blinking 3 times (yellow). If not repeat procedure.
7.3
Adjusting of full-scale
Simulate temperature for full-scale at input of TMU100V with a resistor or a decade for Pt 100. Press
button Zero shortly.
Storing of value is confirmed by LED 4…20 mA blinking 3 times (yellow). If not repeat procedure.
7.4 Output current / output voltage
To change output to signal 4…20 mA keep button full-scale pressed until LED 4…20 mA (yellow) is on.
To change output to signal 0…20 mA keep button full-scale pressed until LED 4…20 mA (yellow) is off.
Output for voltage remains 0…10 V, independently from current output.

Factory setting
Default setting ex works of input/output is
0…200°C / 0…20 mA.
