Changing easy-Drive™ Electric Actuator On/Off

Input Configuration from Single Dry Contact

Control to Dual Dry Contact Control

Supplement to Fisherr L2e Electric Level Controller Instruction

Manual (D103531X012)

This supplement contains information for converting the easyDrive Electric Actuator from Single Dry Contact Control

Mode to Dual Dry Contact Control Mode.

The Dual Dry Contact Control Mode of operation has proven to be a superior and reliable method of operation with the

easyDrive actuator. This method provides a more stable switch actuation by reducing, or eliminating, the switch

bounce that may be associated with the Single Dry Contact Control Mode.

Refer to the appropriate easyDrive Electric Actuator instruction manual for cautions, warnings, and instructions on

removing the easyDrive actuator cover.

Note

This procedure is for easyDrive Electric Actuators configured for ON/OFF INPUT only.

L2e Switch Wiring Conversion

1. Ensure easyDrive actuator power is turned off and remove cover.

2. Observe easyDrive actuator electrical connector to determine Dry Contact Control Mode.

3. If easyDrive actuator is wired as shown in figure 1, the actuator is already configured as Dual Dry Contact Control

Mode and no further action is required. Replace easyDrive actuator cover and apply power to put system in service.

4. If easyDrive actuator is wired as shown in figure 2, the actuator is configured as Single Dry Contact Control Mode.

Proceed with the following instructions to reconfigure to Dual Dry Contact Control Mode.

5. Loosen binding screw #2 on easyDrive actuator

electrical connector (see figure 2) and remove wire.

6. Install red wire from L2e in easyDrive actuator electrical connector location #2 (marked as “OPEN” or “N.O.”) and

tighten binding screw (see figure 1).

7. Loosen binding screw #3 in easyDrive actuator electrical connector, install blue wire from L2e, and tighten binding

screw (see figure 1).
