Environmental Conditions
Warning
Operation outside the following environmental limits may adversely affect operator safety.
Location Indoor use only
Maximum altitude 2000 m
Temperature range 15°C to 40°C
Maximum Humidity Less than 80% RH (non-condensing) at 31°C
To ensure reliable operation the unit should not be exposed to corrosive agents or excessive moisture, heat or dust.
Do not expose the stage to magnetic fields as this could affect the positioning and homing sensor operation.
If the unit has been stored at a low temperature or in an environment of high humidity, it must be allowed to reach ambient
conditions before being powered up.
The unit is not designed to be used in explosive environments.
The unit is not designed for continuous operation. Typical lifetime is 3.3 million switching operations, which equates to 100 km
of travel – see Chapter 5 for more details.
Mounting
Warning
The safety of any system incorporating this equipment is the responsibility of the person performing the installation.
Caution
Although the module can tolerate up to 8 kV of air discharge, it must be treated as ESD sensitive device. When
handling the device, anti-static precautions must be taken and suitable discharge appliances must be worn.
When handling the stage, take care not to touch the wires to the motors.
Do not bend the wires over the motor spring as this affects the performance of the unit.
Do not allow the wires to contact other moving parts.
The ribbon cable connector is made of plastic and is not particularly robust. Do not
connections. Unnecessary or repeated plugging in and unplugging should be avoided or the connector may fail.
