Caution! Check the identification tags and ensure all
wiring is correct before applying power to the sensor.
* A choice of indicating controllers, providing
temperature display and relay outputs, is also available.

POWER SUPPLY
Use a 24 V DC power supply.
Connect power between the PWR+ and PWR- wires. Do not apply voltage to the incorrect
wires as this will damage the sensor. See “Dimensions and Connections” for wiring.
IMPORTANT: Ensure the power supply is only connected to the PWR+ and PWR- wires, and the
polarity is correct, before switching the power on.
Ensure the supply voltage is suitable for the selected output type. For the 0-10 V DC output,
the supply voltage must be 12 to 24 V DC.
Do not switch the power off and on again quickly. If the power is switched off, allow 15
seconds before switching it back on.
If using the alarm output, choose a load that draws no more than 50 mA when powered from
1.2 to 24 V DC. For example, if the alarm supply voltage is 24 V DC, ensure the load is at least
480 Ω (24 V / 0.05 A = 480 Ω).
