    Mounting 3.2 Panel Mounting 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). Fit four retainer springs on the controller before mounting. The retainer springs are available as accessories (code no.

  • Page 14: Removal From The Panel

    Mounting 3.2.1 Removal From the Panel 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.

    5.4 Configuring Inputs and Outputs 5.4.1 Operating Configuration Pictures Depending on the type of ECL 2000 you are working with and the application you have selected, it may be possible to customize from one to four sensor inputs (S8- S11) and one of the relay outputs (P3). Furthermore, if the ECL 2000 LON option is installed, you can configure four LON inputs (L1, L2, L3, and L4).

    Configuring the ECL 2000 5.4.2 Sensor Inputs The ECL 2000 assumes by default that sensor S8 is used to measure room tem- perature. However, you can redefine the use of this sensor. Likewise, if sensors S9, S10 and/or S11 are not used in the default system setup, you can set up these sen- sors to perform various measurements.
