Digiset Timer
This unit is a universal voltage solid-state
timer that will operate from 19 VAC up to
265 VAC and from 10 VDC up to 120 VDC.
Any time period between 0.1 second and
102.3 seconds is available in 0.1 second
increments and can be set with the dip
switch.
Application of input voltage to the timer
starts the time delay. At the end of the
delay period, the load is energized. To reset,
remove the input voltage to the timer.
To select a time period, simply add up the
selected switches in the “ON” position for the
total time delay in seconds.
This timer provides a delay in the Up Run
circuit.

Bypass Switches
(MH-4 Board version shown)
The Bypass Switches bypass either the Car Door
Contact(s) or the Hall Door Contacts, as required by
the appropriate codes. They may only be used on
Inspection Operation.
The code requires using these switches to run the
car on Top of Car Inspection with the doors open,
instead of putting jumpers around the Door
Contacts.
Moving either of these switches to the Bypass
position will force the car onto Inspection Operation.
WARNING: Use extreme caution
with these switches, and always
make sure it is safe to operate the
car with these switches closed.
NOTE: The Bypass Switches can be permanently removed by popping the
cover off the switch and removing the working parts from the inside of the
switch. This may be necessary if local codes do not allow the switches to be
used. If they are removed in this way, it is not normally possible to re-install
the switches.
