5. TIMER SIGNAL INPUTS (INP A and INP B)
DIP switch selectable pull-up (7.8 K) or pull-down (3.9 K) resistors
determine active high or active low input logic.
Input A Trigger levels: V
IL
= 1.25 V max; V

= 2.75 V min; V
MAX
= 28 VDC
Input B: Trigger levels: V
IL
= 1.0 V max; V
IH
= 2.4 V min; V
MAX
= 28 VDC
Inputs A and B:
Timer Input Pulse Width: 1 msec min.
Timer Start/Stop Response Time: 1 msec max.
Filter: Software filtering provided for relay or switch contact debounce.
Filter enabled or disabled through programming. If enabled, results in
50 msec start/stop response time for successive pulses applied to the
same input terminal.
6. RESET/USER INPUT Programmable Function Input:
DIP switch selectable pull-up (7.8 K) or pull-down (3.9 K) resistor
that determines active high or active low input logic.
Trigger levels: V
IL
= 1.0 V max; V
IH
= 2.4 V min; V
MAX
= 28 VDC
Response Time: 10 msec typ.; 50 msec debounce (activation and release)

PROM retains all programming parameters and
timer/count values when power is removed.
9. OUTPUT:
Relay: Form C contacts rated at 5 amps @ 120/240 VAC or 28 VDC (resistive
load), 1/8 H.P. @ 120 VAC (inductive load)
10. CONNECTIONS:
Internal removable terminal blocks are used for power and signal wiring.
Remove end plates with ¼" nut driver. For LD4 versions, all wiring is on right
side of unit. For LD2 versions, power and signal wiring connections are on
the right side and the relay and serial output options are on left side.
Wire Strip Length: 0.4" (10 mm)
Wire Gage: 24-12 AWG copper wire
Torque: 5.3 inch-lbs (0.6 N-m) max
Cable Diameter: Outside diameter must be 0.181" (4.6 mm) to 0.312" (7.9
mm) to maintain NEMA 4 rating of cord grips.

1.0 INSTALLING THE METER
INSTALLATION
The meter meets NEMA 4X/IP65 requirements when properly installed.
INSTALLATION ENVIRONMENT
The unit should be installed in a location that does not exceed the operating
temperature. Placing the unit near devices that generate excessive heat should be
avoided. The unit should only be cleaned with a soft cloth and neutral soap
product. Do NOT use solvents.
Continuous exposure to direct sunlight may accelerate the aging process of
the front overlay. Do not use tools of any kind (screwdrivers, pens, pencils, etc.)
to operate the keypad of the unit.
MOUNTING INSTRUCTIONS
This display is designed to be
wall mounted or suspended
from a ceiling truss or other
suitable structure capable
of supporting the LDT.
Caution should be exercised
when hanging the display to
provide for the safety of
personnel. If hanging the LDT,
run the suspension cables (or
chains) through the mounting
bracket holes. For wall mounting
use #10-32 size bolts.
