DESCRIPTION
The Apollo Process Time Indicator (Model APLPT) and Module (Model
PBLPT) displays a value representing the time between a beginning and end
point of a process, such as a conveyor oven.
The unit's display will update inversely in relation to the input signal
frequency. As input frequency increases (representing speed), the
APLPT/PBLPT time display decreases, indicating a reduction in the duration of
process time. For example, the baking time through an oven is inversely
proportional to the conveyor speed.
The APLPT/PBLPT is available in two versions: The Decimal Point version,
APLPT4/PBLPT4, that has 4 digits with different modes that provide for
decimal points; and the chronometer display version, APLPT5/PBLPT5, which
will show as its maximum value, 999-59.
The units have a feature called "moving window average". This allows one
time disturbances, or irregularly spaced items to be averaged over eight input
pulses, thus keeping display fluctuations to a minimum while still updating the
display on every input pulse. This feature can be enabled or disabled by a side
panel DIP switch.
The units can accommodate magnetic pickups, logic sensors, and NPN open
collector sensors, as well as switch contact closure sensors.
These units have a self-test feature, which checks all the micro-processor and
display driver circuitry at power-up (if enabled). This self-test can also be used
to test display and scale multiplier select DIP switches to make certain all
switches are functioning properly.
DIMENSIONS In inches (mm)
Note: Recommended minimum clearance (behind the panel) formounting clip installation is 2.1" (53.4) H x 5.5" (140) W.

Power and input connections are made via a removable terminal strip, located
at the rear of the unit. This strip can accept one #14 AWG wire. DIP switches at
the side of the unit are used to program the input configuration and to set the
scale multiplier value.
The Model APLPT has a sealed metal die-cast bezel which meets NEMA
4/IP65 specifications for wash-down and/or dust, when properly installed. Two
mounting clips are provided for easy installation. The Model APLPT has a 0.56"
high LED display, which is readable to 23 feet (7 M).
