Before Ordering

Match the full HL-5391 model, roller dimensions, adjustable lever and mounting arrangement to the installation.
Select contact ratings for the actual AC or DC voltage, load type and NO/NC circuit. Do not apply a resistive rating to a motor load.
Set the lever position and allow sufficient over-travel without using the switch as a mechanical stop.
Confirm the cable entry and sealing arrangement. Isolate power before wiring, adjustment or maintenance.

Frequently Asked Questions

What actuator does the HL-5391 use?

It uses an adjustable metal roller lever with a large roller for mechanical position and travel detection.

What is the contact configuration?

The contact arrangement is one normally open and one normally closed contact (1 NO + 1 NC), with a self-resetting mechanism.

Which current rating should I use?

Use the Electrical Load Ratings table for the actual voltage, load type and contact. Resistive, lamp, inductive and motor loads have different ratings.

How should the lever be set?

Match the lever length and roller position to the operating cam. Allow the required travel and clearance; the operating-characteristic table uses a 31.5 mm lever length.

What should be checked before installation?

Check the mounting dimensions, roller path, cable entry, sealing, electrical load and NO/NC wiring. Installation and maintenance should be performed with the circuit isolated.
