Portable Test Kit #50
An inexpensive, portable test kit, #1278C67G01, is available for
convenient field testing and calibration of all plug-in cards and output
relays. The only power source required is a 120V convenience outlet.
A selector switch allows the operator to test individual cards or to
simulate ATS operation by having the source monitoring cards drive
the time delay cards which in turn drive the output relays, exactly as in
actual use. Calibration checks or changes can thus be accomplished
without necessity of energizing the alternate power source.

2. It may be used to start an engine-generator set at selected
intervals, at least once per week, but without causing the transfer
switch to operate and transfer the load to the generator supply.
At the end of the interval it will cause the engine-generator to
shutdown.
INSTRUCTIONS — TO OPERATE THE ENGINE FOR AN INTERVAL
ONCE EACH WEEK, WITH OR WITHOUT OPERATION OF THE
TRANSFER SWITCH.
1. Extend the tabs of Dial A outwards, except those representing the
time of day for the running of the engine or operation of the
transfer switch.
2. Determine the day of the week for this testing. Install the six brass
pins (called skip pins) in the spokes of Dial B representing the
other six days of the week.
3. Turn Dial A counterclockwise until the special tab at 12:00 midnight
advances Dial B. Turn Dial B until present day of the week is
opposite the copper arrow. Turn Dial A counterclockwise until the
correct time of day (or night) is opposite the arrow on the nameplate.
4. If the interval of running the engine is desired more than one day
per week but at the same time of day, remove the skip pin from
the appropriate spoke of Dial B.
Caution
DO NOT insert skip pins in any spoke when that spoke is pointing
towards the copper arrow
