Running times and rest times
A roller screen can be controlled at different intervals. The method of control will have an effect on
the operation and the lifespan of the tube motor.
•
Most systems have a maximum running time of the tube motor not more than approximately 4
minutes in one direction (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 operation the RB50Eᵖˡᵘˢ
usually has a permitted duty cycle of 10 minutes and the tube motor is thermally stopped after
approximately 15 minutes.
•
If the roller-screen system is operated one or two times a day, there is sufficient time 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 times a day, possibly the tube motor temperature
cannot decrease sufficiently 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 continuously operates at high temperatures.
6.2 Operation
•
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 compatible with an
Automatic Control System (ACS) to make operation together possible.
Refer to the Ridder catalogue or website
www.ridder.com
for more
information. Always refer to the manual(s) of the control components used.
7. COMMISSIONING INSTRUCTIONS
7.1 Commissioning - Conditions and starting points
It is important to fully know the operation of the RB50Eᵖˡᵘˢ limit-switch system in §7.3. After 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 operation, the installer must always
make sure that the limit switch is correctly set.
