Note:

It is not necessary to remove the supply voltage before making any

changes in the setting of the controls. If either threshold or function is

changed the red LED-indicator F is active for a short time for checking pur-

poses. The new settings are immediately active. Depending on the change of

the settings, the output relay might be switched off temporary.

OUTPUT RELAY 1 “Fill/Empty” and 2 “Alarm”

Active Condition depends on the function.

Inactive Condition depends on the function or the device has an internal fault

(see LED-indicator F).

Note:

The output relays are galvanically isolated from the power supply

terminals!

SPECIAL OPERATING MODES

The following special operating modes are available for the ICL:

#2 Volatile

#4 Non-volatile

The factory setting is „#2 - Volatile“. To switch between the special operating

modes consider the following steps:

1. Write down the actual DIP-switch settings

2. Turn off the power supply

3. Change the DIP-switch positions as shown below:

4. Press the MR-button and keep pressed!

5. Turn on the power supply

6. As soon as the LED-indicator F flashes, the MR-button can be released

7. Every stroke on the MR-button changes the special operating mode. The

actual mode is indicated with a special flashlight signal on the LED-indicator

F. The flash signal is composed as follows: Number of operating mode =

number of flashlight signals followed by a short pause. This signal is re-

peated constantly. The last-selected special function mode is automatically

stored.

8. Turn off the power supply

9. Restore the original DIP-switch settings

10. The device can be put in operation again
