4 Commercial Refrigeration Parts ECM20/ECL60 Installation and Operation Manual Accessing and Using the Menus Resources are organised into menus which are accessed by briefly tapping the key ( Basic Commands menu) or by keeping the key pressed for more than 5 seconds ( Programming menu). Either do not press any keys for 15 seconds (time-out) or press the key once,to confirm the last value displayed and return to the previous screen. Basic Commands Menu Access the Basic Commands menu by pressing and releasing the key. If no alarms are active, the SEt label appears. By pressing the and keys you can scroll all folders in the Basic Commands menu: - AL: alarms folder (only visible if an alarm is active); - SEt: Set point ting folder. - Pb1: probe 1 folder; - Pb2: probe 2 folder **; - dit: interval between defrosts folder; - det: defrost timeout folder; - dst: defrost end temperature folder **; (** models ID971 and ECL60 only) Setting the Set point: To display the Set point value press the key when the SEt label is displayed.the Set point value appears on the display. To change the Set point value, press the and keys within 15 seconds. Press to confirm the modification. Change the value of the dit, det and dst defrost parameters in the same way. Displaying the probes: When the Pb1 or Pb2* label is displayed, press and the associated probe value will appear (* Pb2 is only present on models ID971 and ECL60). Basic Commands Edit Lock It is possible to disable the keypad on this device. The keypad can be locked by entering the Basic Commands menu using and pressing and within 2 seconds or by programming the LOC parameter (see dis label folder) With the keypad locked you can still access the Basic Commands menu by pressing to display the Set point and dit, det and dst parameters, but you cannot edit them. To disable the keypad lock, repeat the locking procedure. 4 For friendly service and advice in Australia visit your local Heatcraft branch or call

6 Commercial Refrigeration Parts ECM20/ECL60 Installation and Operation Manual Passwords The password PA1 allows access to the programming parameters. In the standard configuration the password is disabled (value = 0). To enable it (value 0) and assign the required value, enter the Programming menu, in the folder with the dis label. If the password is already enabled it will be required to access the Programming menu. To enter it: 5 secs If the password is incorrect, the display will show the PA1 label and you will have to repeat the entry procedure. Manual Defrost Cycle Activation To manually activate the defrost cycle, hold down the key for 5 seconds. If the defrost conditions are not satisfied - the parameter OdO 0 (Models ECM20, ID971 and ID974) - the evaporator probe Pb2 temperature is higher than the defrost end temperature (Models ID971 and ID974) the display will flash 3 times, to indicate that the operation will not be carried out. Diagnostics Alarms are always indicated by the buzzer (if present) and the alarm icon. To switch off the buzzer, press and release any key, the relative icon will continue to flash. NOTES: If alarm exclusion times have been (see AL folder in the parameters table) the alarm will not be signalled. A probe 1 (Pb1) malfunction alarm will appear directly on the display with the indication E1. Models ID971 and ID974: A probe 2 (Pb2) malfunction alarm will appear directly on the display with the indication E2. 6 For friendly service and advice in Australia visit your local Heatcraft branch or call

8 Commercial Refrigeration Parts ECM20/ECL60 Installation and Operation Manual Mechanical Assembly The instrument is designed for panel mounting. Make a hole of 29x71 mm, insert the instrument and fix it using the brackets provided. Do not mount the instrument in humid and/or dirty places; it is suitable for use in ordinary polluted places. Ventilate the place in proximity to the instrument colling slits. 70mm 29mm 71mm 67mm 74mm 32mm Electrical Wiring Attention! Never work on electrical connections when the machine is switched on. The instrument is equipped with screw terminal boards for connection of electrical cables with a diameter of 2.5 mm2 (one conductor only per terminal for power connections). For the capacity of the terminals, see the label on the instrument. In the model ID 974 with Switching power supply only one voltage free relay output is present, on all other models on the contrary all relay outputs are voltage free. Do not exceed the maximum current allowed; in case of higher loads, use an appropriate contactor. Make sure the power supply voltage complies with the one required by the instrument. In 12V versions the power supply must be provided by a security transformer with the protection of a delayed 250 ma fuse. Probes have no connection polarity and can be extended using a regular bipolar cable (note that the extension of the probes affects the EMC electromagnetic compatibility of the instrument: pay extreme attention to wiring). Probe cables, power supply cables and the TTL serial cables should be distant from power cables. Conditions of Use Permitted Use For safety reasons the instrument must be installed and used according to the instruction provided and in particular, under normal conditions, parts bearing dangerous voltage levels must not be accessible. The device must be adequately protected from water and dust as per the application and must also only be accessible via the use of tools (with the exception of the frontlet). The device is ideally suited for use on household appliances and/or similar refrigeration equipment and has been tested with regard to the aspects concerning European reference standards on safety. It is classified as follows: according to its manufacture: as an automatic electronic control device to be incorporated by independent mounting; according to its automatic operating features: as a 1 B-type operated control type; as a Class A device in relation to the category and structure of the software. Unpermitted use Any other use other than that permitted is de facto prohibited. It should be noted that the relay contacts provided are of a practical type and therefore subject to fault. Any protection devices required by product standards or dictated by common sense due to obvious safety reasons should be applied externally. Liability and Residual Risks ELIWELL CONTROLS SRL shall not be liable for any damages deriving from: - installation/use other than that prescribed and, in particular, that which does not comply with safety standards anticipated by regulations and/or those given herein; - use on boards which do not guarantee adequate protection against electric shock, water or dust under the conditions of assembly applied; - use on boards which allow access to dangerous parts without the use of tools; - tampering with and/or alteration of the products; - installation/use on boards that do not comply with the standards and regulations in force. 8 For friendly service and advice in Australia visit your local Heatcraft branch or call
