1 Unpacking the unit and conditions of use Before and when unpacking the unit, make a visual inspection to identify any possible damage which may have occurred during trans- portation. Please look for loose parts, dents, scratches, etc. Report any damage immediately to the freight company. (Please see “Conditions if damage has occurred”.) In other instances, the latest edition of the “General conditions for the supply of goods and services” issued by the ZVEI (German Central Association for the

If the unit is used for purposes other than those stated here, it shall not be considered to be use for the purpose intended. I Only connect sensors supplied with the unit. If a replacement sensor is required, only use sensors of the same type (Part No. H61007 ). I The controller is not intended for use in vehicles because the possi- ble operating voltage ranges, interference level and environmental operating exceed the limits for which the controller can be used. I Please take the application

I If the unit cannot be operated without the risk of danger, it must be taken out of service and precautions taken so that it cannot be switched on again unintentionally. This applies, in particular, if: u the housing has damage which is visible, u the unit is no longer operational or u it has been stored for a long time in unfavourable conditions. I The unit must not be opened. If it is thought that the unit may be defective, send it back to the dealer or manufacturer with a precise descript

I Snap – in housings: Fit the unit in an aperture 28,5 x 70,5 mm and secure it with the relevant mounting frame. a) housings with terminal box coverplate (max. wall thickness 22 mm) b) housings without terminal box cover plate (max. wall thickness 18 mm) for walls thicker than 10 mm: remove lateral plastic spacers from the mounting frame. For the final fixing of the unit the side screws have to be tightened carefully. I Use a cable clamp to secure sensor T1 in a suitable position. 5.2 Electri

* Instructions: I For PCR-110 the total current via terminal 5 of the common relay connection must not exceed 10 A. I Pay attention to the contact loading of the relay (8A/5A resistive load, 2A/1A inductive load). As a general rule, contactors are recommended. I The 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. I It is advisable to use shielded sensor extension cables. All

6.1 Switching on the operating voltage The controller is started by means of a control switch provided by the customer. The first time the controller is started, pre-programmed setting values are used which at a later point can be adapted for individual require- ments. If alarm “AL 2” (temperature in refrigerated chamber too high or too low) is displayed when the controller is switched on, this can be cleared by pressing the key. 6.2 Display During normal operation the current cold store tempera

I Access to the programming level is by pressing the and key at the same time for 5 seconds. The parameters to be changed can then be accessed by pressing the and keys. I To exit from the programming level and save the data, press the key after the last input parameter. If no key is pressed in the programming level for 1

If the measured temperature is higher than the one displayed, set the positive difference as the programming value (e.g. 2K). The temperature display is then corrected by the set value. 8 Maintenance The controller does not require any maintenance. It does not have any fuses so, if brief voltage spikes occur, the refrigeration system will not stop operating for a prolonged period. Once the disturbance has pas- sed, the controller will automatically start up again. Cleaning the housing: Only a dr
