INSTALLATION AND
OPERATING INSTRUCTIONS
1020 SERIES 30/60-WATT LED INFARED ILLUMINATOR
8000-1794-01, REV. A
6
Secondary Connections
•
Pass the low-voltage wiring through the
previously installed 3/8-inch bushing (Figure 4).
•
Open a ferrite clamp and route the wires
through it, then close the clamp.
•
Secure the ferrite clamp to the inside of the
enclosure by means of the double-sided tape
provided.
•
Tighten the bushing.
If using the 2-wire system, leave the two
jumpers in place between –S/-V and +S/+V. If
using the 4-wire system, remove the two
jumpers (Figure 6).
Note:
Terminal #4 on the terminal strip is not
used.
•
Connect Output –S (if used) to terminal #5
•
Connect Output –V to terminal #6.
•
Connect V to terminal #7.
•
Connect S to terminal #8.

Power Supply Operation
120Vac/230Vac Operation
The 1040-3060PSA Power Supply is designed to
operate on 120Vac to 230Vac, 50/60Hz without
the need for adjustment or jumpers.
1040-3060PSA Power Supply Output
Voltage
Before connecting the 1040-3060PSA Power
Supply to the Illuminator, verify and, if necessary,
adjust the power supply output voltage to 13.5
±0.1Vdc.
Measuring the 1040-3060PSA
Output Voltage
•
Verify jumper clip are installed from +S to +V
and from –S to –V on the terminal strip (Figure
6).
•
Connect a DC voltmeter across the +S/+V and
the –S/–V terminals.
•
Connect the proper input supply voltage
(120Vac or 230Vac) to the input terminals.
•
Confirm a reading of 13.5 ±0.1Vdc. If
necessary, adjust the Voltage Adjustment
Potentiometer VR51.
Adjusting the 1040-3060PSA Output
Voltage
The Voltage Adjustment Potentiometer, labeled
VR51, is mounted on the printed circuit board
(Figure 6).
Using a suitable screwdriver, carefully adjust VR51
to obtain 13.5 ±0.1Vdc, measured across the
output terminals (+V and –V).
Caution:
Output voltages over 15Vdc activate the
1040-3060 over-voltage protection circuit. Reset
the circuit by disconnecting the source voltage
from the 1040-3060 for a minimum of 60 seconds.
Two-Wire Connections
Two-wire connections are for power supplies that
do not have remote sensing capabilities (see
Power Supply Selection, page 2). Two-wire
connections are acceptable for installations
requiring short wire lengths between the power
supply and the Illuminator, or where the use of
large-gauge wiring is acceptable.
Notes:
•
Long wire lengths induce voltage drops
between the power supply and the Illuminator,
resulting in reduced IR output and a loss of
viewing range.
•
The 1020 Series Illuminators require a stable
13.5 ±0.1Vdc input to maintain peak IR
wavelength emission (see Figure 9. LED
emissions, page 10.
Table 1 (for 30-watt Illuminators) and Table 2 (for
60-watt Illuminators) list the recommended AWG
wire size for the distance between the power
supply and the Illuminator when using 2-wire
connections.
