Installation Precautions
(continued)
Precaution
Action
Reason
Voltage drop across
the power bus
Use suitable gauge wire in relation to
distance and current draw to prevent
voltage drop.
Operating DC voltage is 24V ±10%
When running long distances from a DC
power supply, the voltage drop during motor
operation across the power bus may be
significant (may drop below 15V!). If there is
a large enough drop in voltage, the roller(s)
may behave in a strange manner. In order to
prevent this, a larger gauge wire must be
used.
Grounding
The conveyor frame should be at the
same potential reference as earth
ground. Standard grounding practices
should be followed.
Static discharge may interfere with general
logic processing, and in possibly damage IC
components on the circuit board.
Environment
Ambient temperature is 32~104°F
Ambient humidity is < 90%RH
Atmosphere has no corrosive gas
Vibration is < 0.5G
Indoor use only
Extreme environmental variables may cause
poor or no performance and damage the
card.
Over-speeding
Over-speeding of the roller’s no-load
speed by more than 50% may cause
damage.
Back EMF will be generated.
Electrical
24V DC ±10%
2A maximum current limiter
(motor lock is 2A)
Diode protection for miss-wiring
Sensor power short circuit protection
5A fuse per motor driver for power
supply protection
Improper power will damage the card.
The motor/card should not be subject to
locked conditions repeatedly.
Internal fuse is not replaceable. If the fuse
has blown, more serious damage has
occurred within the card/motor.
