3.2 Descripon
RPD drive units feature an enclosed housing and sealed limit-switch
system. The drive units are applicable at ambient temperatures of
0-60°C. An expansion chamber with membrane maintains a low
oil pressure in the drive unit, even at high temperatures. A venng
plug is not necessary. This expansion chamber keeps the oil inside
the gearbox in opmum condion. The gearbox is both rain and
wind resistant, and can be installed in any posion.
All RPD drive units are equipped with a double-sided output
sha and a self-braking worm-gear transmission. This two-stage
transmission makes sure that the drive sha is locked when the
drive unit does not move. The RPD is available in 115, 208-480, 230,
380, 400 and 600 VAC models with a torque of 150, 300 or 450 Nm (refer to §3.1). An RPD can be
hand-driven by means of the hexagon bolt in the electric motor sha.
The RPD drive units are equipped with a linear limit-switch system with duty switches, safety
switches and a Fail-Safe mechanism. The Fail-Safe mechanism locks the limit switch. The maximum
switching range (minimum-maximum) of the limit-switch system is 1-36 revoluons of the drive
sha at 3 rpm (revoluons per minute) or 3-61 revoluons at 5 rpm. Models with 150 Nm and 3
rpm (150-3, 1-phase 3-wire) are thermally protected with a PTO switch.
RPD drive units have a lightweight aluminium housing and are supplied with sprockets, the
necessary keys and fasteners.
3.3 Applicaon
The RPD drive units are used in poly greenhouses for driving venlaon systems and roller screen
systems. For other (dierent) applicaons approval from Ridder Drive Systems is necessary.
1 Connuous venlaon
2 Push-pull screening.
NOTE: REFER TO “ATTENTION”!
Sidewall venlaon with
carriage.
Sidewall venlaon with sliding cardan-
sha.
If a switching range of more than 61 revoluons is necessary, RPD
drive-units are not applicable.
Thus, push-pull systems with RSD250 rack drives and a secon size of
5 m or more are not possible.

SAFETY STOP
The motor can start and stop automacally without a warning.
Persons can be in danger of life if they touch a system that is in
operaon.
The motor can start and stop automacally without a warning but
will stay energized. De-energize the system during work on the drive
unit or the system. Persons can be in danger of life if they touch a
system that is in operaon.
A drive unit can get high temperatures. If necessary take protecve
precauons to prevent injuries.
The waing me must be approximately 2 seconds when you change
the direcon-of-rotaon. The electric motor must stop.
This prevents that it connues in the inial direcon.
When a “safety stop” (safety switch) occurs:
• Do a check of the condition of the operated system. Make sure
that the system can be safely operated.
• Do a check of the condition of the limit-switch system (switching
cam --> switching spring). If necessary: Unlock the “Fail Safe”
position (§7.5). Make sure that the system can be safely operated.
• If necessary: Adjust the end positions again.
This prevents damage or injury.

6.2 Direcon-of-rotaon of RPD motor gearbox
The illustraon that follows shows the direcon-of-rotaon A and B of:
1. The input sha (direcon-of-rotaon of the motor)
2. The worm-gear transmission
3. The RLS limit-switch system. The connecon nuts move in the same direcon (A or B)
4. The output shas. Refer to A and B on the gearbox housing.
6.3 Operaon
An RPD motor gearbox can be operated by an intelligent control unit (Ridder MotorControl RMC).
Operaon is also possible together with one or two of the control components that follow:
• Automac control system (ACS)
• Manual control (MC).
Refer to the Ridder catalogue or website ridder.com for more informaon. Always refer to the
manuals of the control components used.
6.4 Safety funcons and stop funcons
The RPD motor-gearbox has the safety funcons and stop funcons that follow:
1. Stop at an adjusted end posion when a duty switch is operated
2. Stop when a safety switch is operated if a duty switch not disconnects
3. Keep duty switches and safety switches disconnected (Fail-Safe: mechanical protecon) when
the limit-switch system , accidentally and not sensed, turns too far
4. Lock the posion of the drive sha, when the drive unit is stopped, because of a self-braking
worm-gear transmission
5. Thermal-overload protecon of the electric motor with a built-in PTO switch. (The model with
150 Nm and 3 rpm (150-3, 1-phase 3-wire).)
