clock power supply.
4. Since all electronic instruments are sensitive to voltage
spikes, pay close attention to the following:
a. If possible, supply power to the electronic time
clock from a phase different than the one supplying
power to the load.
b. Provide a suitable Varistor or RC network across
the INDUCTIVE LOADS supply terminals to reduce
voltage spikes.
c. Place a diode across the DC OPERATED
INDUCTOR terminals to eliminate back EMF.
d. HIGHLY INDUCTIVE LOADS, especially
fluorescent lights, may require a relay in which
case, then Step a and Step c apply.
The time clock can be surface or flush mounted. Lift off the
front cover and loosen the two screws on opposite corners.
Pull off the base's plug with a left to right rolling motion.

Surface Mounting Inside Panel

1. Place screws through the base's preset holes and
screw to back of panel or wall.
2. Wire according to the instructions in the following
section. Depending upon the specific installation, you
may find it more convenient to complete wiring before
attaching the base.
3. Place the terminal cover over the terminal block by
aligning the two screws with the corner holes in the
base.
4. Push the timer firmly onto the plug in the base.
5. Tighten the two screws. A base for DIN rail mounting is
optional.

Wiring the Time Clock

1. Wire 24, 120, or 220 VAC to input terminals. Make sure
to apply correct voltage. Using incorrect voltage will
void the warranty.
2. Connect wire to the screw terminals according to the
unit wiring diagrams. Use 12 to 22 AWG wire.

Remote Human Interface Panel

Installation

Human Interface (HI) Panel

The HI enables the user to communicate necessary unit
operating parameters and receive operating status
information from within the occupied space.
The HI displays top level information in the LCD window,
unless the operator initiates other displays, for the various
unit functions. It also displays menu readouts in a clear
language 2 line, 40 character format. The 16-key keypad
allows the operator to scroll through the various menus to
set or modify the operating parameters. See figure below to
reference the Human Interface (HI) panel keypad.

Remote Human Interface Panel
The remote human interface (RHI) panel is identical to the
unit mounted HI with the exception of the "unit select" key.
This key allows the operator to switch from one unit to the
next to program or view status information regarding a
particular unit.
The RHI functions the same as the unit mounted HI with
two exceptions. The first is the test start function. The
operator can view the service parameters, but can only
initiate the service test function at the unit. The RHI door
has a locking screw to deter access by unauthorized
personnel. Additionally, the RHI can control up to four
different units.

Location Recommendations

The HI microprocessor module is mounted inside a molded
plastic enclosure for surface mounting. It is not
weatherproof. Therefore, it is only applicable for indoor
use.
Locate the RHI panel in an area that will ensure the
communication link between the panel and the unit(s) does
not exceed 5,000 feet maximum or pass between
buildings. See Table 26, p.
The run length of the low voltage AC power wiring to the
remote HI must not exceed three ohms/conductor. Refer to
Table 26, p. 45.
