  • Page 3: Unpacking The Unit And Conditions Of Use

    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”...
  • Page 4: Function

    Please take the application limits into account (see Technical Data in section 11). 3.2 Function PCR-100 and PCR-110 are general-purpose thermostats, each with a relay output and wide temperature control range (–55 °C to +50 °C). The controllers have different housings: PCR-100: Modular housing for 35 mm standard rails PCR-110: “Snap-in”...
  • Page 5: Safety Precautions

    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: the housing has damage which is visible, the unit is no longer operational or it has been stored for a long time in unfavourable conditions.

    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.
  • Page 7: Operation Of The Controller

    Instructions: For PCR-110 the total current via terminal 5 of the common relay connection must not exceed 10 A. Pay attention to the contact loading of the relay (8A/5A resistive load, 2A/1A inductive load). As a general rule, contactors are recommended.
  • Page 8: Switching On The Operating Voltage

    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.
  • Page 9: Adjusting The Cold Store Temperature

    Input values are always changed using the key held down. Input parameters, e.g. the switching difference is shown as “E” with a 2-digit number, e.g. “E 01”. Access to the programming level is by pressing the key at the same time for 5 seconds. The parameters to be changed can then be accessed by pressing keys.

    If the time interval between two defrost cycles is changed when the system is in operation, the new time interval will not be applied until after the next time defrosting has occurred.

  • Page 12: Maintenance

    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.
