4.3.4 Functional Description
The AEC-VS is equipped with:
•
Pulse input for connecting inductive proximity sensors with NAMUR interface
• Pulse input for connecting inductive proximity sensors with 3-wire interface
• Analogue input for the connection of rotary encoders with current interface 0/4 - 20 mA or
position indicators from actuator drives with current interface 0/4 - 20 mA
• Non-failsafe, digital output (typically configured for ’Fan ON’)
• Analogue current output 0/4 - 20 mA
• Analogue voltage output 2/0 - 10 V
• Non-failsafe, digital input (typically configured with ’Fan fault’)
Channel configuration
Parameters are scaling the channel feedback.
•
AEC-VS configuration lower range (P 48, P 50)
• AEC-VS configuration upper range (P 49, P 51)
The type of the used input must be set in ’AEC-VS configuration input’.
Setting the parameters require a reboot of the system.
