ECL 2000 is available in two versions with different input/output configurations.

ECL 2000 Type 1 has 14 preprogrammed applications designed as 14 standard

system setups and type 2 has 17 preprogrammed applications.

The purpose of this installation manual is:

•



To describe how to install and configure ECL 2000, and

•



To provide the installer with system and wiring diagrams for each application

and type.

For a detailed description of regulation and setting parameters, see ECL 2000

Cable Knockouts

The base plate is provided with a number of knockouts for cable entry. The neces-

sary knockouts are removed, and cables and wires are entered through the removed

knockouts to establish connection to the terminal blocks.

Figure 3 shows the ECL 2000’s base plate.

Cable Fixation

For fixation of cables entered through knockouts, you can use the diaphragm nip-

ples enclosed in the packing.

Alternatively, use cable glands as follows:

•



Cable gland PG9 (knockout ø16)

•



Cable gland PG11 (knockout ø19).

The ECL 2000 can be mounted in three different ways: on wall, in panel, and on

DIN rail.

The controller comes with a Quick Guide which must be attached to the inside of

controller’s door (see Figure 6 on page 6).

 :DOO0RXQWLQJ

For mounting on wall, you use a base plate with associated case (code no.

087B8099).

Note:

When deciding where to place the controller, remember that you must leave suffi-

cient space for cable installation.

1.

Place the base plate on the wall and accurately mark the positions of the

three fixing holes. Remember that the arrow on the inside of the base

plate must point upwards (see Figure 4).

Figure 4. ECL 2000 base plate with fixing hole positions and terminal blocks fitted

2.

When all three holes are drilled, the base plate can be fixed with the three

ø3 screws.

3.

Fit the terminal blocks to the back plate and connect wires (for informa-

tion on electrical connections, see page 11).

4.

Mount the case.

5.

Position the controller in the case as shown in Figure 5.

To remove the controller from the case:

1.

Remove the fixing screw (see Figure 6).

2.

Hold the controller by the edge of the front panel and carefully work the

controller backwards and forwards to loosen the connectors on the con-

troller’s rear side from the terminal blocks.

For panel mounting you must use a cutout of 92 x 138 mm. The maximum sheet

thickness of the front plate is 3 mm (see Figure 7).

1.

Fit four retainer springs on the controller before mounting.

The retainer springs are available as accessories (code no. 087B3076).

This set consists of four springs and two terminal blocks.

2.

Make the electrical connections to the loose terminal blocks.

3.

Insert the controller into the panel cutout (see Figure 7).

Figure 7. Panel mounting

4.

Fit the terminal blocks to the connectors on the controller’s rear side as

shown in Figure 8.

The terminal blocks are coded to prevent mains voltage section from be-

ing connected to low-voltage section.

When the controller is mounted in a panel cutout, the easiest way to remove it is to

depress the retainer springs from the rear and press the controller out of the cutout

(see Figure 7, page 7). If there is no access to the rear of the controller, it can be

tilted out of the cutout by inserting a screwdriver in the two recesses provided at

both ends of the unit. Then carefully turn the screwdriver to twist the controller out

of the panel.

The controller can be mounted on a 35 mm DIN rail.

1.

Fit the spring to the rear of the base plate before mounting on the DIN

rail (see Figure 9).

The spring is available as an accessory (code no. 087B3077).

If more than 3 wires need to be connected to the same terminal, use the loop termi-

Note:

When choosing cable type and dimension for installation, local government regu-

Note:

Wire resistance can cause measurement error. For example, a resistance of 4

Ω

cor-

responds to a measured temperature increase of about 1 degree.
