SPECIFICATION WRITER’S GUIDE
The time switches shall be of duty cycle type, capable of programming at
15-minute intervals of the day. Schedule tabs shall be captive on the dial,
and shall be easily set by hand without tools to obtain or to change the
desired schedule. The switching condition shall be maintained when adja-
cent tabs are set alike. The unit shall be powered by a self-starting enclosed
120 (or 208-277) volt synchronous motor capable of continuous accurate
operation. The switch mechanism shall be a self-contained unit rated at not
less than 20 amps, 120 volts, single pole, double throw, and shall be readily
replaceable in the field.
FOR 8001 ADD: The time switch shall be similar and equal to Tork Model
8001. FOR 8007 AND 8007V ADD: An omitting device shall be furnished as
an integral part of the time switch, to enable the switching operation to be
skipped for any preselected day or days of the week. The time switch shall
be similar and equal to Tork Model 8007 or (8007V.) FOR 8007L ADD:
(Same description as for 8007). The unit shall incorporate an integral elec-
trically wound spring reserve power unit, which shall power the clock mech-
anism for up to 16 hours on a power failure. The time switch shall be similar
and equal to Tork Model 8007L. FOR 8001U: The unit shall be furnished
with built-in 480-120V transformer to operate timing motor in parallel with
480 volt load. The time switch shall be Tork Model 8001U.
