The keypad can be locked by entering the “Basic Commands” menu using

set

and pressing and within 2 seconds, or by programming the “LOC” parameter (see “diS” folder). If the keypad is locked, the “Basic Commands” menu can be accessed and the Setpoint displayed, but the value cannot be modified.

LOADING DEFAULT APPLICATIONS

The procedure used to load one of the default applications is:

• when the instrument switches on, press and hold the

set

key: the label “AP1” will appear;

• scroll through the various applications (AP1-AP2-AP3-AP4) using the

and keys;

• select the desired application using the key

set

(“AP3” in the example) or cancel the procedure by

pressing the key

; alternatively wait for the timeout;

• if the operation is successful, the display will show “y”, otherwise “n” will appear;

• after a few seconds the instrument will return to the main display.

ACCESSING AND USING THE MENUS

Resources are organised into menus. Press and release the

set

key to access the “Machine Status” menu.

To access the “Programming” menu, press the

set

key for more than 5 seconds. If no keys are pressed for over 15

seconds (Timeout), or if the

key is pressed, the last value to appear on the display is confirmed.

LOCK SETPOINT MODIFICATION

The instrument can be switched off by pressing the key for longer than 5 seconds. In this condition, the adjustment algorithms and defrost cycles are disabled and the text “OFF” will appear on the display.

67mm

The device is designed for panel mounting. Drill a 29x71 mm hole and insert the instrument; secure it with the special brackets provided. Do not install the instrument in damp and/or dirty places; in fact, it is suitable for use in places with ordinary or normal levels of pollution. Keep the area around the instrument cooling slots adequately ventilated.

Alarms are always indicated by the buzzer (if present) and the alarm icon

To switch off the buzzer, press and release any key; the corresponding icon will continue to flash. N.B.: If alarm exclusion times have been set (see “AL” folder) the alarm will not be signalled.

In the event of an alarm caused by a malfunctioning ambient probe (Pb1), the indication “E1” will appear on the display. For a malfunctioning evaporator probe (Pb2), the indication “E2” will appear (IDPlus 971/974 only). Finally, for a malfunctioning Pb3 probe, the indication “E3” will appear on the display.

DIAGNOSTICS

Hold down the key for longer than 5 seconds. It is only activates if the temperature conditions are fulfilled. Otherwise, the display will flash three times to indicate that the operation will not be performed.

the card. If the procedure is a success, “y”, will appear on the display, otherwise “n” will appear.

• Format (Fr): This command is used to format the copy card, (recommended when using the card for the first time).

Important: the Fr parameter deletes all data present. This operation cannot be cancelled.

• Download: Connect the Copy Card when the instrument is switched off. At power-on, data is downloaded from the

copy card to the instrument automatically. At the end of the lamp test, the display will show “dLy” if the operation was successful and “dLn” if not.

NOTE: After downloading, the instrument works with the settings of the new map just downloaded.

LIABILITY AND RESIDUAL RISKS

ELIWELL CONTROLS SRL declines any liability for damage due to:

and/or instructions given in this document;

- use on panels that do not provide adequate protection against electric shocks, water or dust when

assembled;

- use on panels allowing access to dangerous parts without the use of tools;

- tampering with and/or modifying the product;

- installation/use on panels not complying with current standards and regulations.

DISCLAIMER

This document is the exclusive property of ELIWELL CONTROLS SRL and may not be reproduced or circulated unless expressly authorised by ELIWELL CONTROLS SRL itself. Every care has been taken in preparing this document; nevertheless ELIWELL CONTROLS SRL cannot accept liability for any damage resulting from its use. The same applies to any person or company involved in preparing and editing this document. ELIWELL CONTROLS SRL reserves the right to make aesthetic or functional changes at any time without notice.

ELECTRICAL CONNECTIONS

Attention! Make sure the machine is switched off before working on the electrical connections.

The instrument is equipped with screw or disconnectable terminal blocks for connecting electrical cables with a max. diameter of 2.5 mm

(one wire per terminal for power connections): for the terminal ratings, see the label on the instrument. Do not exceed the maximum permissible current; in case of higher loads, use a suitably rated contactor. Make sure the power supply voltage complies with that required by the instrument. Probes have no connection polarity and can be extended using a normal bipolar cable (note that the extension of the probes influences the electromagnetic compatibility - EMC - of the instrument: take great care with the wiring). Probe cables, power supply cables and the TTL serial cable should be routed separately from power cables.

- suitable for storage

- application: air

- climate range A

- measurement class 1 in the range from -25°C to 15°C (*) (* exclusively using Eliwell probes)

NOTE: The technical specifications given in this document regarding measurement (range, accuracy, resolution, etc.) refer to the instrument and not to any accessories provided, such as the probes. This means, for example, that the error introduced by the probe must be added to the typical error of the instrument.

IDPlus 902/961 devices are controllers with 1 relay output, 1 temperature regulation sensor and 1 multifunctional Digital/Temperature input.

IDPlus 971 devices are controllers with 2 relay outputs, 2 temperature sensors (regulation and evaporator), a multifunctional Digital/Temperature input and a digital input.

The relay output can be used to control:

- compressor

- defrost heating elements

- evaporator fans

- AUX output

- temperature alarm

- Standby

The second probe can be used to control the defrost cycle and the evaporator fans.

The Digital inputs (D.I.1 and D.I.2) can be used for:

- Energy saving

- Defrost activation

- AUX management

- door switch

- Standby

- external alarm

- Deep Cooling

- pressure switch

- HACCP alarms

IDPlus 974 devices are controllers with 3 relay outputs, 2 temperature sensors (regulation and evaporator), a multifunctional Digital/Temperature input and a digital input.

Relay outputs 2 and 3 can be used to control:

• compressor

• defrost heating elements

• evaporator fans

• AUX output

• alarm

• Standby

The second probe can be used to control the defrost cycle and the evaporator fans.

The Digital inputs (D.I.1 and D.I.2) can be used for:

• Energy Saving

• Defrost activation

• AUX management

• door switch

• Standby

• external alarm

• Deep Cooling

• pressure switch

• HACCP alarms
