40 years of innovation from the inventors
of solid state data logging
DFR-77 DATA LOGGER
1977 - The world’s first commercial EPROM
data loggers, the MACE DFR-77 were delivered.
Hundreds of these instruments were used
throughout Australia and Papua New Guinea
working under the harshest imaginable
conditions. The EPROM data recording technique
proved to be the most reliable method of
electronic data storage.
HYDROMACE TRS
1984 - MACE introduced the Hydromace system
which gave environmental field stations the combined
capabilities of data logging, control, telemetry via
telephone, radio or satellite and intelligent response to
both computer or human interrogation.
HYDROMACE 2000
1992 - The HydroMace 2000 data logger provided
multi-channel logging and control in water
catchments, sewer treatment plants and industrial
pollution applications. A leader in its time, many
are still in use in catchment management and flood
warning networks across Australia.

2.0 Warnings
2.1 Intrinsic Safety
The HydroMace 3000 is NOT an intrinsically safe instrument and should not be
installed in hazardous (explosive) environments. Should an intrinsically safe
instrument be required, MACE can oer other instruments with this approval
level.
2.2 Floods
MACE recommends that the HydroMace 3000 electronics module be
mounted above known ood peak levels. MACE will not be liable for damage
caused by ooding. (The unit is weatherproof, but NOT waterproof and
should NOT be submerged).
2.3 Sunlight
MACE recommends that the HydroMace 3000 electronics module be
mounted so that the LCD faces in a direction away from direct sunlight (ie
South in the Southern Hemisphere and North in the Northern Hemisphere).
2.4 Cable damage
MACE recommends that all cables be appropriately routed through electrical
conduit or other similar mechanism. MACE will not be liable for damage to
cables, especially if it is caused by vehicles, digging implements, animals or
debris in the pipe or channel.
2.5 Insects and moisture
After the HydroMace 3000 system has been installed and fully tested, MACE
recommends the use of expanding “space ller” foam down the rst 5 to 10cm
(2 to 4 “) of the conduit or mounting pole to prevent insect/moisture ingress.
2.6 Battery life
Care must be taken when a mains power supply is used to charge the internal
battery instead of a solar panel. If the mains power remains disconnected
for an extended period of time, the internal battery may be permanently
damaged.
2.7 Electromagnetic compatibility (EMC)
This is a Class A product. In a domestic environment this product may cause
radio interference in which case the user may be required to take adequate
measures.
3.0 Installing HM 3000 power options
3.1 Solar panel installation on a 2” pole
The solar panel is used to charge the internal battery of the HydroMace 3000
where mains power is unavailable.
Users are advised to ascertain the suitability of solar panels for
their application by checking relevant solar radiation maps for
their region (for example those found at http://rredc.nrel.gov/
solar/old_data/nsrdb/redbook/atlas/ ). As a guideline, for an
HM 3000 with three I/O cards and measuring every ve minutes,
at least three hours sunlight is required per day
1. Place an M8 bolt with M8 at washer through the hole in left arm of the
mounting bracket. Ensure that the head of the bolt is on the INSIDE and the
thread faces outward.
2. On the OUTSIDE of the bracket, place an M8 spring washer then an M8 nut.
DO NOT TIGHTEN THE NUT.
3. Repeat these two steps on the right hand side of the bracket.
4. Holding the solar panel carefully, hold it above the two arms of the
mounting bracket.
5. Slide the solar panel down so that the head of each of the M8 bolts ts in
the channel on either side of the solar panel.
Ensure that the gutter of the solar panel is positioned between
the at washer and the head of the M8 Bolt
7. Place the u-bolt provided in the solar panel mounting kit around the pole.

8. Place the solar panel mounting bracket onto the u-bolt. Ensure that the
arms of the bracket face out from the pole and that the mounting hole on
each arm is towards the top of each arm.
9. Slide the bracket to the desired position on the pole, taking care to place it
at the desired height and so that the open face of the bracket faces towards
the sun.
10. Place the 3/8” at and spring washers on to the U-bolt and tighten the two
nuts so that the bracket is secured on the pole.
11. Tilt the solar panel so that the active side faces towards the sun (North in
Southern hemisphere, South in Northern hemisphere) at an angle specied
in the data sheet provided. (your latitude + 15°).
11 12
12. Now tighten the M8 nuts on each side of the mounting bracket to secure.
13. The cables from the solar panel/charger to the electronics unit must be
enclosed to minimise exposure to the elements. The cable should be either
routed through conduit or through the solar panel mounting pole. You will
need a hole drilled in the mounting pole at the top near the solar panel as
well as a cut away where the electronics unit is to be mounted. Refer to the
pictures below.
13 13
3.1 Solar panel installation on a 2” pole - Continued
14. Ensure that the cable from the solar panel is terminated using the threepin connector provided in the electronics box and that the polarity is correct.
The photo below shows the location of the three-pin connector inside the
HM 3000.
15. The polarity is labelled on the circuit board near the connector in the

3.2 Installing a MACE mains powered trickle charger
In certain applications or where the use of a solar panel is impractical or
undesirable, the HM 3000 can be powered from any DC source of 16-30 Volts
(2Amps).
When the ambient temperature is less than -10°C (14F), the battery
should be removed to avoid permanent damage to the battery. The
HM 3000 should be powered by an external power source
1. The charger available from MACE (Part No. 850-323) comes complete with
a circular barrel connector that plugs directly into the electronics module.
The barrel connector for the 16-30VDC charger input is centre positive
2. Alternatively, if a DC source other than a MACE charger is used, this
is terminated using the same three-pin connector as for the solar panel
described above.
3.3 Powering the HM 3000 with an external battery
In certain applications, it may be desirable to power the HM 3000 with an
external battery.
1. The HM 3000 can be powered by an external 12V battery through the
dedicated “External Battery 12V” terminal. See photos below.
2. If a solar panel is connected to the HM 3000 as in Chapter 3.1, the internal
charging circuit of the HM 3000 will also charge the external battery. The
charging circuitry of the HM 3000 has a 20 Watt capacity.
If the external battery is charged via its own solar panel and NOT
through the HM 3000 charging circuit, the internal HM 3000
battery will discharge completely

3. Hold the electronics module up against the pole so that the oval cut-away
on the pole matches the cable entry point. Route the sensor and power
cables through the cable entry point as shown.
IMPORTANT: Apply NON-ACIDIC cure silicon sealant to the back of the
electronics module in the channel around the cable entry point. This will
stop water owing down the pole and into the electronics module
4. Use the two “U” bolts, 3/8” nuts and 3/8” washers provided to secure the
electronics module to the pole.
Do not overtighten the pole mounting bolts as permanent
damage may occur to the electronics enclosure
5. Plug in both the sensor cable and solar panel cable into the sockets as
shown in the picture below.
Sensor cables should be looped prior to connecting to act as a
form of strain relief.
Ensure that the cable from the solar panel/charger is terminated
using the three-pin connector provided in the electronics box and
that the polarity is correct. The polarity is labelled on the circuit
board near the connector
6. If using a 16-30VDC mains charger then plug this into the socket shown
in the picture below. Alternatively, the charger may be wired into the solar
panel screw terminal block (to the left of the socket).
7. Once all the cables are connected the system should be fully tested.
Assuming everything is connected and fully functional the cable entry point
should be lled with expanding “space ller” foam. This is to prevent insects
and/or moisture damaging the system.
