The unit is equipped with an opto-decoupled electronic alarm output.

Take note of the alarm output limit values.

ISupply voltage: Max. 250 V AC.

IMinimum load: 40 mA

IMaximum load: 80 mA

IIf an inductive load (contactor or horn) is connected, connect an RC element directly at its coil.

Instructions:

IPay attention to the contact loading of the relay

(8A / 5A resistive load, 2A / 1A inductive load). As a general rule, contactors are recommended.

IThe maximum tested sensor cable length is 50 m, with a minimum cross section of 2 x 0.75 mm2. Solder the extension cable to the sensor cable to prevent contact resistances.

IIt is advisable to use shielded sensor extension cables.

All shields must be routed at the side of the controller to one earth/protective potential. The extension cable shield must not be connected on the sensor side, otherwise bonding currents may occur via the shielding.

IThe controllers are designed respecting the highest degree of immunity to interference. If the local interference level exceeds the immunity data might get lost (AL1 in display) and the controller switches to the preprogrammed setting values. This is not a mulfunction of the controller. In such cases the means to suppress interference have to be improved (RC-elements, shielded lines).
