General advice

PLEASE READ BEFORE USING THIS MANUAL

 This manual is part of the product and should be kept near the instrument for easy and quick reference.  The instrument shall not be used for purposes different from those described hereunder. It cannot be

used as a safety device.

 Check the application limits before proceeding  The technical data and information in the user manual could change without obligation to notice.

SAFETY PRECAUTIONS

 Check the supply voltage is correct before connecting the instrument.  Do not expose to water or moisture: use the controller only within the operating limits avoiding sudden

temperature changes with high atmospheric humidity to prevent formation of condensation

 Warning: disconnect all electrical connections before any kind of maintenance.  The instrument must not be opened.  In case of failure or faulty operation send the instrument back to the distributor or to “Dixell company with

a detailed description of the fault.

 Consider the maximum current which can be applied to each relay (see Technical Data).  Ensure that the wires for probes, loads and the power supply are separated and far enough from each

other, without crossing or intertwining.

 Fit the probe where it is not accessible by the end user.  In case of applications in industrial environments, the use of mains filters (our mod. FT1) in parallel with

inductive loads could be useful.

4. REMOTE KEYBOARD

The IC200L/D can be connected with 2 remote keyboard. The remote keyboard can have the NTC probe on board that is used to show the room temperature and also to control the temperature regulation. To connect the remote keyboard it is necessary to use shielded cable for a maximum lenght of 150mt. In case of no communication between the instrument and the remote keyboard the display shows “noL” (no link). Mod. VI620 – standard keyboard Mod VI620S – keyboard with internal temperature probe Use the connection cable CAB/CJ30 (2x0.2 mm2) to interface the IC connector to the shielded wire.

5. FIRST INSTALLING

On Board Clock (Optional)

Giving power supply the bottom display shows “rtC” alternated with a temperature or pressure value: It is necessary to set the RTC.

If the probes are not connected the display shows the corresponding probe alarm messages. In this situation the RTC setup and the programming are available.

ATTENTION The RTC function is an optional and it is not possible to update the instrument but it is necessary to order the instrument already complete of this features.

With power failure the RTC back-up battery maximum duration is 1 week. After this period it is necessary to setup the clock again.

Real Time Clock Setup

1. Push M key for 3 seconds until the bottom display shows “Hour” and the top display shows its value.

2. Push SET one time: the value is blinking.

3. Use the Up and Down keys to adjust it. Push SET one time to confirm; automatically the display shows next parameter.

4. Repeat the operations 2. 3. and 4. for all the RTC parameters:

- Min: minutes (0÷60)

- UdAy: day of the week (Sun = Sunday, Mon =Monday, tuE =Tuesday, UEd = Wednesday, tHu = Thursday, Fri =Friday, SAt =Saturday)
