ST 2000 Starter tester with built-in computer for starter motors up to
12 kW
Description
ST-1000
and ST-2000 are simple to use computerized testers designed for real load testing of
starter motors from 2.0 up to 4.0 kW (ST-1000) and from 0.4 up to 12 kW (ST-2000)
respectively.
The
tester is capable of simulating any real operating conditions through a precise computer
controlled hydraulic loading unit, assuring reliability and accuracy of the testing
results. The tested starter is quickly and easily placed into position by means of a 3-way
adjustable slide, which enables precise meshing of the starter drive with the gear on the
loading unit. The drive end housing of the starter motor is fitted on the exchangeable
mounting fixture and is safely secured in place by three adjustable eccentric clamping
jaws. Once the starter is in place, the operator chooses between free run, load or stall
test by shifting of the gear level into the desired position and starts the testing
process by pressing the start button. The tester can be operated in automatic mode for
fully automatic testing or in manual mode for taking the performance parameters of simple
motors or when specific testing is required. Depending on the selected test type, testing
proceeds as follows: |
 | Free Run Test (up to 15 000 rpm)-
Battery Voltage, Solenoid Current, Motor Current and Starter RM are displayed and printed.
|
| Load Test
The starter motor is tested under load of up to 200 Nm for ST-2000 and 100 Nm for
ST-1000. The testing process ends with a load release, simulating operating conditions
after the engine starts. The voltage drop on the solenoid contacts under load is also
measured which allows to evaluate the quality of the contacts. The load test can be
executed in two versions-short load test and full load test. The short test includes
displaying and printing of Load Battery Voltage, Load Current, RPM, Torque, and Output
Power. The full test includes all of the above as well as a display and print out of
all performance curves.
|
| Stall Test
By locking the gear of the loading unit, the starter motor is tested in stall mode.
In stall mode the tester measures maximum torque of up to 250 Nm. The test can be made at
various starting conditions by adjusting the power supply, i.e. cold engine starts at
extreme winter temperatures

| Hydraulic loading
unit - CW & CCW
|
| Automatic Reject
The tester can be programmed to reject a unit automatically if it does not meet the
defined specifications. This test includes comparisons of the parameters of the measured
unit against the required tolerances.
|
| Computer diagnostics
The software application suggests the probable reason for failure of the tested unit. The
computer diagnostics cover open armature, poor connection, bad commutation, defective
leads, mechanical problems (excessive friction in bearing or gear reduction, bent armature
or drive shaft), open solenoid winding, solenoid contacts stuck closed, poor solenoid
contacts etc.
|
| Statistics
The computer can record various data for statistical analysis, i.e. production statistics
(number of failed units of all manufactured units for a determined period of time),
statistical filters (selection in different groups) etc.
|
| Computer controlled
adjustable power supply
The computer controlled power supply can simulate various power sources ranging from 12/24
V with capacity of 45 to 2x180 Ah with adjustable softness.
|
|
Upgradeable memory
Practically unlimited number of combinations of starter motor parameter settings can be
stored in the computer memory.
