Instruction Manual - 48 - The thread tension release signal can be turned on with a delay relative to the thread trimmer. The delay is entered as an angular value in parameter 192. Shut-off takes place in position 2. However, the signal can be extended by the configurable time in parameter 191. Should position 2 not be reached due to mechanical error, the output is turned off after 10 sec. This protects a solenoid with a low permitted activation time from destruction. 6.21.
