User manual HONEYWELL PCR 100

[. . . ] ¼ The controller is not intended for use in vehicles because the possible operating voltage ranges, interference level and environmental operating exceed the limits for which the controller can be used. ¼ Please take the application limits into account (see Technical Data in section 11). 3. 2 Function ¼ PCR-100 and PCR-110 are general-purpose thermostats, each with a relay output and wide temperature control range (­55 °C to +50 °C). ¼ The controllers have different housings: PCR-100: Modular housing for 35 mm standard rails PCR-110: "Snap-in" installation housing, which fits into aperture 28. 5 x 70. 5 mm. [. . . ] Wiring diagram: 6 Instructions: ¼ For PCR-110 the total current via terminal 5 of the common relay connection must not exceed 10 A. ¼ Pay attention to the contact loading of the relay (8A/5A resistive load, 2A/1A inductive load). ¼ 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. 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. ¼ The 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 controllers switches to the preprogrammed setting values. In such cases the means to suppress interference have to be improved (RC-elements, shielded lines). 6 Operation of the controller Front view of controller: 7 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 requirements. 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 temperature is displayed. Two spot indicators show the switching status of the relays during operation: Pos. 6. 3 Functions of keys Never operate the keys with sharp objects (screwdriver or similar). Display of setpoint value Clear alarm messages Manual defrost initiation Display of time until the next defrost Display limit value for excess temperature (cold store sensor T1) Press and hold down key. Press key. Press key. 8 ¼ ¼ ¼ ¼ ¼ Input values are always changed using the or key with the key held down. the switching difference is shown as "E" with a 2-digit number, e. g. 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. 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 10 minutes, this mode will be exited without the data being saved. Do not display altered parameter data before saving the data, as it would be reversed to its original value in the process. 6. 4 Setting the cold store temperature Press and hold down the key. [. . . ] Damage or malfunctioning caused by the equipment being handled incorrectly or by non-compliance with the operating instructions shall not be covered by the warranty. The warranty shall be invalidated if any work is carried out on the appliance. 11 Technical data Mains voltage/frequency: Rated wattage: Display: Resolution: Measuring range: Outputs: 230 V AC ± 10%, 50/60 Hz 2. 1 watts 3-digit, 7-segment LED, red, 14. 2 mm 1K ­55 to +50 °C 1 relay with changeover contact, 8 A, 230 V AC, resistive load 1 relay with N.
