AC / DC CONNECTIONS:
NOTE: Connect power only after other connections
are finished. Do not touch the live AC power
terminals. The unit has been designed with an
isolated AC input, therefore polarity is not a concern
for the AC power. The chasis is plastic, therefore
earth ground is not used. For DC operation, con-
nect +DC to terminal 10 and -DC to terminal 3.
Although the unit is designed to be immune from
line or RF interference, the unit is controlled by a
microprocessor and an electrically "noisy" environ-
ment could cause operating problems. The input
power lines should not be common to power lines
for motors, pumps, contactors, etc.
Four sources of noise can occur:
1) AC power line noise- If the unit cannot be con-
nected to an electrically clean power source, an
inductive load supressing device (MOV as
GE#V130LA1 or Resistor Capacitor as Paktron#
.2uf/220 ohm @ 400V) can be installed. Although
locating the suppressor across the AC supply at the
unit should help, best results are obtained by
connecting the suppressor across the leads of the
"load" at the device causing the spikes.
2) Input line noise- The noise is carried on the input
and DC ground lines. Make sure the input wires are
not run into the unit in a bundle with power input
lines. We recommend using shielded cable. Con-
nect the shield to DC ground of the unit and "earth"
at one point in the circuit preferably at the DC
ground terminal of the unit.
3) Output lines- The unit has two open collector
outputs and two optional relay outputs. When these
outputs are used to run external relays or solenoids,
spikes can be generated upon activation. This
noise can spread through the instrument causing
operating problems. If the source is a D.C. operated
device, a general purpose diode (IN4004) placed
across the solenoid prevents electrical noise spikes.
Connect the cathode (banded side) to the more
positive side of the coil. If the source is an A.C.
operated device, use a Resistor Capacitor or MOV
across the coil.
4) 24 VDC output supply- Noise can be generated
on the 24 VDC output supply if it is used to drive
inductive loads or if the current draw exceeds
50mA. Insure that all inductive loads have a diode
(such as IN4004) across the coil and that the current
does not exceed 50mA.
