Instruction for use

Motor Tester MT40

Operation

Disconnect the motor from the central supply

system.

Set the current measuring range to suit the

maximum current expected.

Connect the measuring cable terminals to

the motor.

Polarity:

CLOSE operation : red = ( + ); black = ( - )

OPEN operation : red = ( - ); black = ( + )

Select the direction of drive / using the

rotary knob. After use the turn the unit back to

"Battery of".

Notes

The electronic protection responds to excess

current, over-discharging and short

circuiting. The red LED lights up.

Checking storage battery capacity:

Turn the left-hand rotary knob to “Batt.” .

Turn the right-hand rotary knob in direction

or .

The full measurement range corresponds

to a voltage of 20 - 30V.

Battery charged : > 26 V

Battery discharged : < 22 V

If the battery capacity is low, the over

discharging protection could respond.

Recharge for 14 hours using the charging

unit supplied. The green charging control

LED lights up.

Protection response in the event of excess

current or short-circuiting:

If the unit's output current exceeds 3A, the

electronic protection is triggered.

The drives must not be in

operation during the charging

process with connected

charging set.

Danger of destruction!

ATTENTION!

Charge storage batterie 14

hours using enclosed charging

set before initial operation!

Full capacity of the storage

battery is developed only after several charge

and discharge actions.

Special Information

- 3 current measuring ranges

- Powerfull 24V NiCd storage battery

- Storage battery capacity display 20-30 V

- Electronic, self-resetting protection by

means of power MOSFET for excess

current, over-discharging and short-

circuiting with LED display.

to use.

Application

On-the spot function check on any kind of 24

VDC motor up to 2A.

For testing, adjusting, initial operation and

maintenance. Can register safe operation,

shutdown reserve and overload.
