RESET AND PROGRAM OPTIONS

Connecting a wire from the RST EN (Reset Enable) or the HS (Program

Enable) Input terminals to Common will enable the front panel Reset or

Program buttons respectively.

Pulling the “RST.” input low causes the counter to reset. The “RST.” can be

pulled low by either a mechanical switch or solid-state transistor switch. The

Switch load is 15 μA (max. voltage drop 0.5 V) when ON. The OFF-state

leakage current must be less than 2 μA.

Note: The RC protection circuit on the “RST.” Input causes a delay of

approximately 15 msec in Reset response.

L.S. INPUT; CONTACT VERSIONS (30 Hz MAX.)

Connecting the “L.S.” Input to Common with a mechanical or solid-state

switch increments the counter. The switch load is 7 A (max. voltage drop 0.5

V) when ON. The OFF-state leakage current must be less than 2 A.

Reed switches, mercury wetted contacts, snap action limit switches, and

silver alloy relay contacts with wiping action are usually satisfactory for input

activation. Motor starter contacts, tungsten contacts, and brush-type contacts

should not be used.
