10.2.7 SIGNAL ERROR -
configuration of signal level fault detection
The SIGNAL ERROR function is used to detect a fault on the input signal.
Fault detection
Fault detection can be selected for a 4 – 20 mA signal only:
Fault if input signal ≤ 3.5 mA (± 0.5 % of final value, hysteresis 0.5 % of final value)
If 0 – 20 mA is selected, sensor break detection cannot be selected.
A signal error is indicated on the device by the red LED for "setpoint error detection" ON.
safety position for sensor break On:
The following configurations can occur with "safety position if setpoint error" ON:
Active SAFE POSITION
If a fault is detected, the drive moves to the lower SAFE POSITION set position.
Inactive SAFE POSITION
If a fault is detected, the drive moves to the end position which it would assume in the isolated state.
10.2.8 BINARY INPUT -
activation of the binary input
This function activates the binary input.
The following settings can be implemented for this:
• Approach the safety position
• Switching over the MANUAL/AUTOMATIC operating mode
• Starting the function X.TUNE (standard valid since software version A.12).
safety position
Approach the safety position.
Active SAFE POSITION function
the drive moves to the lower SAFE POSITION set position.
Inactive SAFE POSITION
The drive moves to the end position which it would assume in the isolated state.
switch over the operating state to manual or autOmatic.
Binary input = 0 → AUTOMATIC operating state
Binary input = 1 → MANUAL operating state
If switching over the operating mode is selected, you can no longer switch the operating mode with DIP switch 4
starting the function X.TUNE
Binary input = 1 → Starting X.TUNE.
