Safety Instructions and Warnings Please read these instructions before installing and starting up the pressure switch. Failure to follow the instructions will make all guarantee, warranty and compensation claims null and void. connection, and the correct tools must always be used.
Exclusion of Liability NOSHOK guarantees that the pressure switch is in perfect working condition when it is delivered. The basis consists of the technical data in the data sheet and these operating instructions. Liability cannot be accepted for the suitability of the pressure switch. Temperature Switch Description The temperature switch has one analog output and one switching output or two switching outputs.

Switching On and Off The temperature switch is switched on when the supply voltage is applied. There is no on/off switch. A brief initialization phase occurs when the supply voltage is applied to the switch. The display and the set point LED illuminate. The measuring range (min- and max. temperature) and the unit are indicated briefly. The outputs are inactive during this time. After initialization the switch is in normal operating mode.

CE – Conformity The switch complies with all requirements of EN 61 326 with regard to interference emission and immunity for use in industrial areas. NOSHOK recommends the use of shielded cables. Installation and cable routing must be carried out correctly in order to maintain the effective protection from electromagnetic interference. Maintenance The temperature switches that are described in this document are maintenance free.
Cleaning The exterior of the 850 Series Temperature Switch can be cleaned using a soft, moistened cloth. Heavy soiling can be removed using a mild cleaning agent. The switch must not be opened for cleaning! Aggressive chemicals or hard scrubbing can damage the surface, particularly the display film. Disposal The packaging and used parts must be disposed of in accordance with the regulations of the country in which the device is installed.
