Running mes and rest mes
A roller screen can be controlled at dierent intervals. The method of control will have an eect on
the operaon and the lifespan of the tube motor.
• Most systems have a maximum running me of the tube motor not more than approximately 4
minutes in one direcon (side-wall screen-height: 2.5m). This makes it possible to open, close
and set a screen system without a thermally stopped tube motor. In operaon the RB50Eᵖˡᵘˢ
usually has a permied duty cycle of 10 minutes and the tube motor is thermally stopped aer
approximately 15 minutes.
• If the roller-screen system is operated one or two mes a day, there is sucient me for the tube
motor to decrease in temperature. The lifespan will not decrease because of this.
• If a roller-screen system is operated too many mes a day, possibly the tube motor temperature
cannot decrease suciently before it is operated again. Because of this the tube motor possibly
operates at a too high temperature and can be thermally stopped. The lifespan will decrease if
the tube motor connuously operates at high temperatures.
6.2 Operaon
• An RB50Eᵖˡᵘˢ tube motor can be operated by a Ridder MotorControl
RMC50 control unit.
• The primary use of Ridder RB50Eᵖˡᵘˢ tube motors will be in automated
roller-screen systems. An RMC50 control unit is compable with an
Automac Control System (ACS) to make operaon together possible.
Refer to the Ridder catalogue or website www.ridder.com for more
informaon. Always refer to the manual(s) of the control components used.
7. COMMISSIONING INSTRUCTIONS
7.1 Commissioning - Condions and starng points
It is important to fully know the operaon of the RB50Eᵖˡᵘˢ limit-switch system in §7.3. Aer that
obey the procedures in §7.4 and if necessary §7.5/§7.6. The warnings that follow must always be
obeyed.
Do not go across the limits of the system. This prevents damage or
injury!
Before the system is put into operaon, the installer must always
make sure that the limit switch is correctly set.
