CYCLES Position
The timer counts in whole
cycles and uses the power
input line frequency as timing
reference.SEC. Position
The timer counts in two selectable increments and uses an internal
10kHz oscillator as timing reference.
.01/.001 Switch
Selects one of two counting increments available for the timer SEC.
mode.
NOTE:
Changing the position of the CYCLE/SEC. Switch (or the .01/.001 Switch while in
the SEC. position) during timer operation will produce erroneous readings.
CONTACTS Binding Posts Circuit controls output and timer in the normally open or normally
closed positions of the STOP MODE Switch.
NOTE:
Do not connect CONTACTS binding posts to an energized circuit.
STOP MODE Switch
Selects either current actuated position to stop the current output and
timer, or either of the two external contact stop mode positions.
NORM. OPEN
With CONTACTS binding posts connected to normally open
contacts, output circuit will remain energized and timer will continue
to run until contacts close.
NORM. CLOSED
With CONTACTS binding posts connected to normally closed
external contacts, output circuit will remain energized and timer will
continue to run until contacts open.
CURRENT
Timer will initiate only when the output circuit is completed and a
threshold current of approximately 8% of full scale of ammeter range
selected is exceeded. Timer will continue to run until output circuit
opens, current drops below threshold level or output is de-energized.
