Product warnings
• Connecting any EKE inputs to mains voltage will permanently damage the controller.
• Battery Backup terminals does not generate power to recharge a device connected.
• Battery backup - the voltage will close the stepper motor valves if the controller loses its supply
voltage.
• Do not connect an external power supply to the digital input DI terminals to avoid damaging the
controller.
General warnings
• Every use that is not described in the manuals of EKE 100 is considered incorrect and is not
authorized by the manufacturer
• Verify that the installation and operating conditions of the device respect those specified in the
manuals, especially concerning the supply voltage and environmental conditions
• All service and maintenance operations must therefore be performed by qualified personnel
• The device must not be used as a safety device
• Liability for injury or damage caused by the incorrect use of the device lies solely with the user
Installation warnings
• Recommended mounting position: Din rail, Panel mounting
• Ensure that only trained and qualified personnel perform installation, start up, and maintenance.
• Ensure that electrical work conforms to national and local electrical codes, regulations and/or
standards
• Before working on the electrical connections, disconnect the device from the main power supply
• Before carrying out any maintenance operations on the device, disconnect all electrical
connections
• Do not expose the device to continuous water sprays or to a relative humidity greater than 90%.
• Do not exposure to corrosive or pollutant gases, natural elements, environments where
explosives or mixes of flammable gases are present, dust, strong vibrations or shock, large and
rapid fluctuations in ambient temperature that might cause condensation in combination with
high humidity, strong magnetic and/or radio interference (e.g., transmitting antenna)
• Use cable ends suitable for the corresponding connectors. After tightening connector screws,
tug the cables gently to check their tightness - Minimize the length of probe and digital input
cables as much as possible, and avoid spiral routes around power devices. Separate from
inductive loads and power cables to avoid possible electromagnetic noises
• Use appropriate data communication cables. Refer to above in present document.
• Minimize the length of probe and digital input cables as much as possible and avoid spiral routes
around power devices. Separate from inductive loads and power cables to avoid possible electro
magnetic noises
• Avoid touching or nearly touching the electronic components fitted on the board to avoid
electrostatic discharges
