L.S. INPUT; VOLTAGE VERSIONS
The CUB7T accepts most machine control voltage signals. The input accepts
AC (50/60 Hz) or DC control voltages from 10 to 300 V. The unit times when
voltage is applied between the LS input and Common.
Any off-state leakage
current may activate the timer.
RESET AND PROGRAM OPTIONS
Connecting a wire from the RST EN (Reset Enable) or the HS (Program
Enable) Input terminals to Common will enable the front panel Reset or
Program buttons respectively.
Pulling the “RST.” input low causes the timer to reset. The “RST.” can be
pulled low by either a mechanical switch or solid-state transistor switch. The
Switch load is 15 µA (max. voltage drop 0.5 V) when ON. The OFF-state
leakage current must be less than 2 µA.
Note: The RC protection circuit on the “RST.” Input causes a delay of
approximately 15 msec in Reset response.
WARNING
: Any lead may be at hazardous live input potential.
External wiring and devices connected to the unit must be rated
the same as applied signal input voltage and be properly
isolated from Class 2 or SELV circuitry.

ORDERING INFORMATION
APPLICATION
A laundromat owner wants to monitor the cost of operating his dryers.
He needs to know how many hours each dryer has operated. A CUB7T100
(Voltage Input; Positive Image Reflective) is mounted on the back panel of
each dryer. The signal input is connected across the motor of the dryer. The
CUB7T will accumulate time while the dryer is running. On a regular basis
the owner records the cumulative
operating hours for each
dryer and calculates if
he needs to make any
necessary adjustments. The
timer can be reset via key
switch.
BACKLIGHT OPTION
Optional backlight versions of the CUB7T require an external 9 to 26 VDC
power supply. The external supply is connected between the V+ and common
terminals as shown in the drawing.
WARNING
: When connecting the wiring for a backlit CUB7T
measuring an AC input voltage, the neutral of the single phase
AC signal is connected to Terminal 1 (COM), and line (hot) is
connected to Terminal 4 (LS). The DC supply for the
backlighting is connected as shown in the drawing. Three phase
AC applications require an isolation transformer.
