MOUNTING
The AR/e controller comes in a rugged, watertight polycarbon-
ate enclosure intended for wall, pipe or panel mounting. The
package contains two sets of mounting screws and "O" rings
which must be used to maintain the NEMA 4X rating of the
enclosure.
When mounting the unit select a location which has adequate
ventilation, protection against mechanical shock and accessi-
bility for operation and service.
Operating Temperature:
32° to 130° F (0° to 55° C)
Operating Humidity:
Up to 85% non-condensing
Using a 5/32'' Allen wrench, remove the four corner screws in
the housing.
Separate the front and rear halves of the housing. Keep the
screws and housing gasket in an accessible location.
WIRING PROCEDURE
Three plug-in terminal block assemblies are provided for
connecting 28 to 14 gauge insulated wire. Solid or stranded
wire can be used.
It is recommended that wiring be carefully planned and laid
out before installation. This will help determine the amount of
space needed for wiring as well as the final location of the unit.
Detail diagrams in this section illustrate proper wiring proce-
dures for all standard and optional functions.
Be sure to comply with the wiring requirements and all appli-
cable electrical codes.
Note: Terminal block assembly unplugs from printed circuit
board for ease in connecting field wiring.
Disconnect all power to the unit before connecting wires to
any of the terminals. Do not use machine power service. A
dedicated or lightning circuit is recommended.
Wall or Pipe Mount
1. Using the appropriate mounting hardware attach the back
part of the housing to the mounting surface.
2. Wire the unit (see wiring procedures on this page).
3. Carefully place the housing gasket in place and bolt the
front part of the housing to the back part.
Panel Mount
1. Use the housing gasket to mark and drill the panel.
2. Drill a 3/4" hole in the panel for the fuse holder.
3. Wire the unit (see wiring procedures on this page).
4. With the housing gasket properly placed on the front
housing, mount the unit to the panel.
POWER INPUT
The AR/e is designed to work with a 110 VAC power supply. In
case of power failure, the unit will retain all programmed
values and continue to count down (without display or output)
for several hours. When power is restored, the unit will send an
output signal if enough pulses have accumulated during power
outage. If the power down period exceeds the battery capacity,
the last known batch count and other programmed values will
be stored until the power comes back on. (Battery requires a
minimum of 24 hours to recharge from a fully discharged
condition.)
INSTALL BATTERY ON CIRCUIT BOARD ONLY
AFTER WIRING IS COMPLETED.
