d. Connect to the syringe driver a 9 V DC power supply.
e.
Set the rate dials to read 99.
f.
Start the syringe driver.
g.
Load the actuator with a weight of 4.5 kg. Reduce VR5 until the
driver starts to stall.
h. Reduce the load to 4 Kg. Allow the driver to run for a minimum
of six motor pulses and then replace the 1/2 Kg weight. The
driver must stall at 4.5 Kg within 6 motor pulses. If it will not
stall, repeat step (e).
3.
7 Volt thrust test
a.
Reduce the power supply to 7 V DC and set the actuator 10 mm
from the end of travel.
b.
Start the syringe driver running and allow two motor pulses.
Load the actuator with a 3 Kg load. The unit must run for six or
more motor pulses without stalling
c.
Reset the power supply to 9 V DC.
d. Remove the driver from the Thrust rig.
4. Guard test
a.
Temporarily short pin 20 (IC1) to + rail. Hold down the
START/TEST
pushbutton and check that the motor starts and
then stops in 5 - 10 seconds.
b.
Remove the short from pin 20.
5.
Flash frequency
a.
Set rate to 00 mm/hr, start normal running and monitor the front-
panel LED flash period.
b.
The period between flashes should be 1.029 seconds (minimum) -
1.071 seconds (maximum), i.e. 1.050 seconds ± 2%. Adjust R9 if
necessary.
c.
Alternatively, if using a timer/ counter, the flash frequency
should be set at between 0.97143 Hz (max) and 0.93333 Hz (min).
d. The flash frequency should not change by more than 1.5% when
the supply voltage is reduced to 7 volts.
