1. Power the simulator with 120V AC 60 Hz.
2. Connect the actuator extension cable between the three pin connector in the center of the front
panel (fig 1) and the connector at the end of the actuator.

4. Contact type selection and insertion resistor value.
The rotary switch allows the activation or deactivation of contact resistance.
The resistive states of the closing and opening contacts are independent, which makes for great
flexibility in configuring tests.

7. Manual close and open tests.
-To close, press the Close button (fig. 13). The actuator produces a physical displacement, and
the contact state indicator becomes red (fig. 14).

Note 2 : The rear panel fuse is a 20 amp fuse that protects the magnetic driver coils in the actuator unit
(fig. 17).
