WARNING!
The controllers are designed for operation under the following ambient
conditions (IEC 61010-1):
Overvoltage category II, pollution degree 2
Avoid exposure to the following factors:
■
Direct sunlight or proximity to hot objects
■
Mechanical vibration, mechanical shock (putting it down hard)
■
Soot, vapour, dust and corrosive gases
■
Potentially explosive environments, flammable atmospheres
■
Ambient temperature: 0 ... 50 °C (32 ... 122 °F), without sudden changes
■
Humidity: 35 ... 85 % relative humidity without condensation
■
Not to be mounted close to electromagnetic switches or cables carrying
high currents
■
Not for direct contact with water, oil, chemicals or their vapours.
WARNING!
■
Failure to comply with this can destroy the sensor input.
■
These controllers feature neither a built-in switch nor a fuse. It is therefore
necessary to fit these into the circuit outside the controller (recommended
fuse: slow-acting, rated voltage AC 250 V, rated current 2 A).
■
Carry out the PID auto tuning in a trial run.
■
Never touch any live terminals. This may cause an electric shock or
problems in operation.
■
Before working on the connection terminals or cleaning the controller,
switch off the power supply to the controller.
■
The area of the actual display can easily be damaged. Avoid any contact
with hard and sharp objects, or any excessive pressures.
