S-DRIVE - INSTALLATION PG DRIVES TECHNOLOGY
SK76745/10
Check that the status indicator remains on, or flashes slowly, after one second.
Go to drive the scooter slowly in the forwards direction until you hear the solenoid brake operate. The scooter may
start to move.
Immediately release the throttle. You must be able to hear the solenoid brake operate within a few seconds.
Repeat the test in the reverse direction.
9.5 Test Drive
Drive the scooter and make sure that it operates correctly for all positions of the user controls.
9.6 Soft-Stop Test
Drive the scooter at full forward speed and switch the controller off.
The scooter must not stop suddenly, but should decelerate to standstill.
In addition, ensure that the requirements in section 1.3 of this chapter are satisfied.
10 Electromagnetic Compatibility (E.M.C.)
The S-Drive Scooter Controller series has been tested for compliance with the EMC requirements of EN12184, the FDA and the
FCC. The guidelines in this section will help you to make sure that your scooter installation will meet the requirements of the
directive. You should consider EMC and perform relevant tests as early as possible in the design phase.
10.1 Emissions
A typical scooter and S-Drive installation have been type tested and have passed the requirements of EN55022 Class B.
Observe the following recommendations to minimize radio frequency emissions:
10.1.1 Motor Suppression
Solder a suitable suppression capacitor between the brush holders of each motor, inside the motor cases. Keep the lead length
as short as possible. We recommend a value of 4n7F 250V AC ceramic. The maximum value you should use is 10nF. A typical
type is Roderstein WY0472MCMCF0K.
For 4 pole motors, a capacitor should be fitted between each pair of brushes.
10.1.2 Cables
You do not need to use screened battery and motor looms, but:
Keep the length of all wiring to a minimum.
Make sure the loop area of the wiring is minimized. Route the positive and negative wires to each motor together.
Route the battery positive and negative wires together. Where possible, route the battery and motor looms
together.
Secure the motor and battery looms to the scooter frame over as much of their length as is practical.
Do not use the controller connectors as the junction points for the battery connections. Separate junction points
away from the S-Drive should be provided for the other scooter electrical functions.
