Power (torque limit*) modification
From the “Home” screen (actuator unlocked) or during operation :
Press the Power selector (4) downward to increase power
o
D1-1=>D1-2=>D1-3=>D1-4 or D2-1=>D2-2=>D2-3=>D2-4
Press the Power selector (4) upward to decrease power
o
D1-4=>D1-3=>D1-2=>D1-1 or D2-4=>D2-3=>D2-2=>D2-1
* When setting the JA73 power, the maximum torque that the actuator can
perform (stall torque) is impacted. This setting allows choosing different torque limits.
See next page for the torque limits values.
6.
Starting the actuator
Once the actuator is unlocked, press the safety trigger (2) and the throttle button (3).
You can control speed by pressing more or less the throttle button (3). The number of triangles
shown indicate the percentage of the actuator maximum speed which is used.
When the actuator is running, the screen displays the remaining autonomy in hours (x.xx
H
)
or in minutes (xx
M
) if the autonomy becomes less than one hour.
This time is an estimate that takes into account the speed and power used since the last
reset and varies over time.
It also displays the battery charge icon, the “Eco” mode icon (if power is 1 or 2), the rotation
direction (D1/D2), the power level (1 to 4) and the speed indication (1 to 4 triangles)
7.
Advanced information’s available :
You can access the menu when the motor is idle only. Each press on the Power button (1) changes the menu with the following
path:
Rotation direction
Working time since the last reset
Average power since the last reset
Energy used (kWh) since the last reset
Total number of actuator working hours
Number of hours remaining before the next maintenance required
Language : French or English

CMT version
Hold power button pressed 3s to modify a value or to reset to zero.
Press the Power selector or press the throttle (3) once while holding the safety trigger (2) to escape the menu and go back
the Home screen.
5. Electronic torque limiter
a.
General info
The Portable Valve Actuator JA73 is equipped with an electronic torque limiter that makes it stop when the desired torque is
reached. This way, material is protected against excessive torques that might damage it. It can also be used as a proof that
a sufficient torque has been applied to a handwheel for example.
Each JA73 model allows 4 different power settings that give 4 different maximum torque limits.
