MC89E/S Electric series
1. Instruction manual
Light, powerful and fast, modec PVAs (Portable Valve Actuators) offer improved safety and
comfort for operators and protect equipment from damage. They can be adapted to all types of
handwheels, keys and valves, and have a torque that can reach up to 850 Nm (620 lb.ft).
They come with a large number of options, adaptors and accessories so they can be assembled
to best meet the particularities of different maneuvering systems and their environment.
This makes it the perfect tool for any valve type, indoor or outdoor, with a great autonomy. Its
two 18V Lithium-Ion batteries allow to use it continuously during up to one hour. For an even
more intensive usage, use the main power connection kit that plugs on the actuator just like a
battery and provides an unlimited autonomy.
Designed for any type of operation, the MC89 comes with 3 models only that cover a 0 to 450
rpm speed range and a 850 Nm (620 lb.ft) maximum torque. No need to say that even the most
stubborn valves can be operated! No worry though, the integrated electronic torque limiter will
easily prevent any damages for your valve or the tool itself. The integrated electronic torque
limiter prevents from any risk of damaging the valve or the actuator itself.

account of fixed points, straps, chains and any other torque retention system used.
To protect the operator, we recommend that you do not use the PVAs if there is a risk of
lightning.
Safety of personnel during use and maintenance
Stay vigilant –watch what you are doing and apply common sense when using the tool. Don’t
use a tool if you are tired or under the influence of drugs, alcohol or medicines.
Use the individual safety protection equipment (see the summary table, page 7).
Don’t rush ahead – maintain a suitable position and balance at all times.
Wear suitable clothing –don’t wear baggy clothes or jewelry. It is obligatory to tie back hair
and to wear close-fitting clothes (not floaty) to ensure all clothing parts are distanced when
moving.
To avoid the motor starting at the wrong time, before picking up or while carrying the PVA,
remove or disconnect the battery and/or unplug the wire from the main.
Use and servicing
Don’t use the tool if the switch systems for changing direction, accelerating, starting up or
stopping are not working properly. This could pose danger to the operator.
Observe tool maintenance. Check there if no incorrect alignment or blockage of moving parts
or from broken parts or any other problem that could affect how the tool functions. If there is
any damage, take the necessary steps and precautions to return the tool and its accessories
to good working order.
Have the tool serviced by a qualified repairer using only modec products when changing
parts.
Only use valve accessories recommended and approved by modec. Think to consult the
accessory list provided and/or seek advice from modec for specific uses.
Before starting up the motor, the operator must, without fail, check the follow points:
-Accessories mounted or activated by the actuator are in good condition and correctly
attached.
-The most suitable torque retention system is being used and it assures the safety of the
operator.
-The system that fixes to the valve or the handwheel is adapted to the valve or handwheel
being actuated.
-Both the actuator and the operator are in a stable position. The operator is placed in
opposition to any possible movements the actuator may make while coming to a stop.
Stop the actuator immediately if it starts to behave differently (a change of noise, increased
vibrations). Replace all damaged parts of the actuator and accessories. Damaged parts can
burst and cause serious harm, even a potential fatality.
Before placing a handwheel on, or removing it from, the actuator, wait until the actuator has
come to a complete stop.
Only activate the command to inverse the direction left/right when the actuator is fully
stopped, otherwise the operator may find they are working in a poorly adapted position.
Always hold down the rotation direction switch until it stops.

In certain circumstances, the tool may keep rotating for several seconds after releasing the
switch. Never put your hands close to the tool or any moving parts.
Keep the ventilation slits on the actuator and the batteries free and clean to ensure adequate
cooling.
Keep the contacts on the machine, charger and battery pack clean.
Don’t open the battery. Risk of short-circuiting.
Protect the battery from heat, for example direct exposure to the sun, to
fire, to water and to humidity. There is a risk of explosion.
In case of damage or non-conforming use of the battery, vapors could
escape. Ventilate the work place and consult a doctor if you feel unwell.
a. Transporting the actuator
Keep the original casing for return in case of any revisions or repairs.
When packing, make sure that all switches are off and without any constraints.
Always pack the tools in the correct spaces to avoid them knocking against each other.
Replace the batteries in their allotted casing.
Lithium-ion batteries are subject to rules regulating the transport of dangerous materials.
The operator can transport the batteries by road without taking any additional measures.
When transporting via a third party (for example, by air or a via a transport company), you
must conform to the specific measures regarding packaging and labelling. In such a case,
it is imperative to take advice from an expert in the transport of dangerous materials
when preparing the transportation. Only send the batteries if the packaging is not
damaged. Recover any unprotected contacts and pack the batteries tightly so they
cannot move about. Please also follow any additional regulations that may apply.
b. Storing the actuator
modec actuators must be stored in a dry and correctly ventilated environment to ensure there
is no corrosion of the internal mechanic parts.

(see table below) All performance values indicated above have a +/-5% accuracy
Use with a Banjo head
Banjo heads enable to use the actuator on a handwheel with a rising stem. They also
add a gear ratio to the system by reducing the speed and increasing the torque by 4
for the BJH01 and by 3 for the BJH02. However, the BJH01 cannot withstand an output torque
higher than 600 Nm (440 lb.ft). As a consequence, the input torque should not exceed 150 Nm
(110 lb.ft). The BJH02 cannot withstand an output torque higher than 1000 Nm (740 lb.ft). As
a consequence, the input torque should not exceed 330 Nm (240 lb.ft).
When using a Banjo head, it is essential to set the electronic torque limiter so that the input
torque will not exceed 150 Nm (110 lb.ft) for the BJH01 and 1000 Nm (740 lb.ft) for the BJH02.
Failure to observe these precautions can lead to premature aging of the banjo head and even
breakage.

Instructions for use :
The battery pack is delivered partially charged. To guarantee
that the battery pack provides full power, charge it completely
in the charger before using it for the first time. It can be charged
at any time without reducing the battery life. Interrupting the
charging process does not damage it. The battery pack is fitted
with a temperature sensor, which only permits charging at
temperatures of between 0 °C to 55 °C. This ensures a longer
battery life.
The battery pack should ideally be stored in a cool (5°C to
25°C) and dry location (air humidity < 80 %). Significantly
shorter operating times after each charge indicate that the battery pack is worn and should be
replaced with a new one. Observe instructions regarding disposal.
Capacity display:
When pressing the button,[1-1] the charge indicator [1-2] shows the charge of the battery
pack during approx. 2 s :
3 LED : Battery pack is charged > 70%
2 LED : Battery pack is charged between 40% and 70%
1 LED : Battery pack is charged between 15% and 40%

13
1 LED flashing: Battery pack is charged < 15% Charge the battery pack before any
further use. Do not continue until complete discharge.
After the portable actuator has switched off automatically, do not press the on/off button,
this could damage the battery pack.
7. Starting up the Portable Valve Actuator
a. Changing the battery pack
INSERTING / REMOVING THE BATTERY
Before using the battery pack, check that the battery
interface is clean. Any contamination of the battery interface
may impair correct contact and lead to the contacts being
damaged. A faulty contact may result in the machine
overheating or being damaged.
b. Settings
Risk of injury! Only adjust the settings when the power tool is switched off and free of
any load.
CHANGING DIRECTION OF ROTATION
Switch to the left = “D1” rotation direction / Right / clockwise
Switch to the right = « D2 » rotation direction / Left / counterclockwise
SETTING TORQUE LIMIT AND SPEED
The maximum speed value can be set with the Speed control trigger (8) on the top of the
actuator. There are 4 possible positions. The torque limit can be set with the thumbwheel
located at the bottom back of the actuator.
Each combination of speed and torque settings provide different rotational speeds and torque
limits. The matrix hereafter shows the values for each combination. Once the desired torque
limit is reached, the actuator beeps twice and stops. It restarts only after releasing and
pressing the power switch again
The torque also depends on the selected speed:
Pos 1: Moderate speed / Max torque
Pos 4: Max speed / Moderate torque

8. Setting up the Portable Valve Actuator
a. General info
The actuator must be kept stable while turning the valve or handwheel.
modec Portable Valve Actuators can be used in any position.
However, to ensure the operator is working safely and in the best conditions, it is imperative
that the actuator is used in the axis of the handwheel being activated.
NB: These diagrams are made with one of the modec actuators. However, the head (flange and
output shaft) being identical on all actuators, they apply in the same way to all the actuators of
the range.
b. Fixing the actuator on to the torque management device and/or on an
adaptor
To ensure the operator is working safely and in optimum conditions, it is imperative to use
a torque retention system.
Our actuators are delivered with:
A BR001 torque management reaction bar
A strap or a chain
2 carabiners.
In addition to this basic pack, modec also has a wide range of torque management accessories
(see the catalogue and the following presentation for more details).
As well as these standard accessories, modec
develops specific systems. If you would like to
check your installation or if you have a specific
solution request, contact a registered modec
distributor”
Besides this torque retention rod, it is also
possible using the “modec standard” flange and
shaft to fix the system to RA30 right-angled
models, to BJH hollow heads and all modec
torque management accessories (see
catalogue).
If the standard equipment does not provide a
torque retention that offers sufficient safety for

both operators and equipment, modec can develop and/or adapt special torque management
systems.
Never use a portable actuator with a torque management system that is under-sized, unstable
or badly positioned.
c. Fixing the BR001 torque management arm and anchoring strap
Pull each fixation spring with the ring and rotate for a quarter turn so that they stay in the pulled
position. Place the black ring of the torque management bar on the flange so that the 6 pins
enter the corresponding holes. Make a quarter turn with the fixation springs rings and release
the springs making sure they come back. Check that the torque management bar is properly
secured to the flange.

The chain must remain
in the plane of the reaction
bar and must not work at an
angle greater than ± 30 ° to
the perpendicular of the bar.
Except if otherwise engraved on the
torque reaction system, the maximum torque
is 1000 Nm (740 lb.ft)

9. Using the actuator
a. Preliminary checks
1 –Check the equipment is in good condition and use accessories that are the most
suitable for the actuator.
Make sure the torque management system and the handwheel adapter are compatible with the
action about to be carried out.
2 –Insert the battery. Set the torque limiter to minimum.
3 –Check the rotational direction required for the valve or the handwheel. Set the defined
rotation direction using the actuator’s left/right switch.
4 –Position the adaptor on the valve and set up the torque retention system. Consult the
instructions for adaptors.
5 –Check that the strap is fixed on the appropriate side of the reaction bar depending on the
rotation direction
Handwheel direction D1
Handwheel direction D2
6 –When starting up, always start up slowly in order to VERIFY the rotational direction, and to
put tension on the torque retention strap or chain.
b. Torque reaction safety stop
In case you don’t use a torque reaction system or you don’t install it correctly, the actuator may
rotate suddenly and unexpectedly when started. If the rotation speed is high, this may be
dangerous for the user. In such a case, in order to protect users, the actuator will switch off,
beep once, and the LED light will flash continuously.

Release the On/Off switch
Install a correct torque reaction system
Press the On/Off switch again
c. Potential problems when actuating a valve
1 –If the actuator sounds a “beep” it means that the required torque is higher than the torque
limit set. Increase progressively the torque limit and try again.
Make sure that the torque limit set doesn’t exceed the valve maximum allowed torque
2 –If the actuator is still unable to start even with a high (or maximum) torque limit, the valve
may be fully open or closed and the selected direction of rotation may not be correct. In this
case, repeat the procedure from the beginning by changing the direction of rotation of the
actuator.
Check again the direction of the torque retention.
3 –In case of resistance resulting from deposits on the stem, turn the valve in both directions
several times to ‘clean’ it. modec revolution counter (optional) enables you to always know
which position the valve is in.
4 –When the closed position is reached, make sure the torque does not exceed the valve
maximum allowed torque. Unless the procedure indicates otherwise, reopen the valve with a
few turns so that the accelerated fluid “cleans” any potential impurities from the valve, then
close it again at the desired torque.
5 –When the maximum open position is reached, reclose with a few turns to avoid the valve
getting stuck in future. Doing this also means that the valve is still able to turn when next
actuated even if the operator turns it the wrong way, which again helps prevent the valve being
stuck.
10. Revolution counter (option)
PRESENTATION
The digital Revolution counter adds up the
revolutions in one direction and subtracts
them in the other direction in such a way
that the operator always knows where he
is in relation to the initial set-up. The tool
also measures and shows the rotational
speed.
Note 1 : The instant speed indicator needs several revolutions before it can give a stable and
regular speed. In light of this, you have to wait several seconds to get a reliable reading.
Note 2 : The screen turns itself off after 5 minutes.
