Changing easy-Drive™ Electric Actuator On/Off
Input Configuration from Single Dry Contact
Control to Dual Dry Contact Control

Supplement to Fisher™ 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.

Refer to the L2e instruction manual (D103531X012
Partner, or at Fisher.com

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.

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

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).
