GENERAL OVERVIEW
The
ACT-3X
digital panel meter is an extremely versatile instrument. The user has complete control of the unit configuration.
Power may be either 115 - 230 Vac (50/60 Hz), or optionally, 12 Vdc or 24 Vdc. Input signals are accepted (on Channel 1) from
optical, proximity, magnetic, infrared or laser sensors, or direct TTL or external AC sources. A second AUXiliary input
(Channel 2) may be used for instrument control and remote resetting. There are several remote communication options – RS232,
USB or Ethernet and the optional remote software can be used to program the unit or display data locally. The unit is suitable for
panel mounting or bench top use, with convenient screw terminal connections on the rear panel of the instrument.
When the instrument is turned on, it displays all 8s, then ―3 rx.x‖, where 3 is the unit type (ACT3) and rx.x is the software
revision level, before entering the normal mode of operation.
The display will show ―- - - - -‖ when a measurement is over range.

INSTALLATION
The instrument is intended to operate in the following environment:
Indoor Use Only
Installation Category II
per IEC 664
Pollution Degree Level II
per IEC61010-1
Measurement Category I
per IEC61010-1
Altitude
up to 2,000 m
Temperature
-10 °C to +50 °C operating per IEC61010-1
Humidity
Maximum relative humidity 80% for temperatures up to 31°C decreasing linearly to 50%
relative humidity at 40°C
AC Mains Supply
100 - 240 Vac ~ +10% 50/60 Hz 8 VA
DC Supply (Option)
12 or 24 VDC+10% 6 watts (DC Option)
NOTE:
The instrument is designed to be panel mounted and as such should be considered as fixed
equipment or permanently connected. If permanently connected, disconnection from the supply
must be possible via a customer supplied switch or circuit breaker rated at 120V or 240V
(dependent on local voltage supply) 5A minimum when connected to an AC supply or 30V 1A
minimum when connected to a DC supply. This disconnection device must disconnect all current-
carrying conductors. It must be included in the panel installation and should be clearly marked, in
close proximity to the Unit and easily accessible to the operator.
The ACT3X is a 1/8 DIN enclosure requiring a 3.58‖ wide by 1.74‖ high (91x44 mm) mounting hole. Approximately 5‖ (127
mm) will be required behind the panel. Refer to Figure 1 below.
Before installing, check the power
supply requirements on the rear
panel. Remove the mounting clips,
if fitted, and install the unit into the
panel from the front. From the rear
of the unit, install the mounting
clips into the slots on each side of
the unit and tighten the mounting
screws against the front panel.
WARNING: Do
not
over
tighten the mounting screws.

WARNING:
Do not use this instrument in any manner inconsistent with these
operating instructions or under any conditions that exceed the
environmental specifications stated.

Noisy Environments
These instruments are highly responsive. They have input ranges up to 999,990 RPM and 250,000 Hz. They therefore have
extremely fast input circuitry that may respond to spurious noise. It is important to provide a clean source of power to the
units, either AC or DC, and to ensure that the input to the unit is free of spikes or any other high frequency noise. In noisy
environments, it may be necessary to supply power through a filter, or alternate source. The inputs may also need to be
