The front panel of the CX300 is a sealed membrane keypad which
E
provides excellent protection for most industrial environments. The time
R
or count setpoint is entered using the increment and decrement keys for
S
each digit position. The SET and ENT keys provide access to the
setpoint, as well as to the front panel programmable software functions.
These programmable functions control the pulse output length, setpoint
to zero or zero to setpoint cycle progress indication, and count input
scale factor. The software programming functions are indicated by
prompts to help the user program these functions without the need for
written instructions.
■ Keypad lock function allows viewing of setpoint, but does not allow
unauthorized changes
■ 4 1/2 digit (19999) liquid crystal display - .5 inch high digits
■ Annunciators (right of the display) flash to indicate timing or counting
■ Two form C instantaneous contacts and two form C programmed
contacts
■ Five time ranges from 19.999 sec. to 199 hr.: 59 min.
■ Three count rate input rate speeds are programmable with a max.
count display of 19999 - can be extended via count input scale
factor
■ 24, 120, or 240 VAC operations
■ Count input available for 120 volt AC or low voltage AC/DC
operations
■ When programmed as timer, count input circuit serves as time inhibit
(without resetting the unit)
■ Non-volatile memory data retention

OUTPUT OPERATING MODES
ON-Delay Operation
The contacts are energized at the end of the timing/counting cycle
and remain energized until the unit is reset.
Interval Operation
The contacts are energized during the timing/counting cycle and
then shut off at the end of the cycle.

Pulse and Repeat Operation
The contacts are energized at the end of the timing/counting cycle for a
pulse which is user programmable. At the same time that the cycle is
completed and the pulse output begins, the timing/counting cycle resets
and begins again. This repeat operation continues as long as the start
circuit is energized.
