    TLIMITERR Checkout time of the correction variable If upon the expiry of the checkout time, the valid measuring range is not reached, then the DULCOMETER ® Compact Controller exhibits the following behaviour: LIMIT ERR: The control is switched off. An error current is emitted, provided the output is configured as a measured variable output TLIMITERR: The control is switched off.

    Control parameters and functions ‘LIMIT’ can be used to set The parameter a limit for the control variable. If the con‐ trol variable exceeds this limit value, the CHECKTIME fault is triggered (checkout time of the control has elapsed). The con‐ trol is switched to basic load and a fault current output.
