RAMP TIME: You can select the slow start time (acceleration) from 0.2 to 2 seconds. This option is mainly
used with self-tapping screws. Reaching the torque while the ramp is still on will result in inaccurate torque
output.
SPEED: You can select any speed value of the screwdriver between nominal (max) speed and 65% of max
speed .
N.B.
The torque range is ensured only at the nominal speed of the screwdriver. Should you need to set lower
speeds, please check if the screwdriver stops correctly at the pre-set torque. In HARD JOINT the pre-set
speed only relates to the Brake Time; the second (slower) speed will be automatically chosen by the unit
depending on the preset torque.
REV TM: This option will automatically start a reverse cycle after a torque reached signal or a max TIME.
You can select a time between 0 (function excluded) and up to 10 seconds. During the reverse cycle, it is
necessary to keep the start lever pressed (or the start contact closed) otherwise the screwdriver will stop
before the pre-set time.
To progress to the second screen, push MENU again.
Second screen: SETUP CYCLE
You can modify the cycle parameters: Number of screws, Rejected screws, Min and Max Screwing Time,
Unscrewing, New program contact, Free cycle or Sequence.
SCREWS: number of screws in each Program, from 1 to 99.
REJECT: number of rejected screws allowed in each single cycle. Screws which result in NOK (Not OK -
see below) may or may not be repeated if it has been set as rejected or zero. You can set up to 9 rejected
screws.
If the number of rejected screws exceeded, the main screen changes with OVER and the screwdriver stops.
To start again, push ESC or RESET contact.
If OVER appears during a sequence, there are 2 possibilities:
RESET SINGLE CYCLE > push ESC or close the RESET contact for 1 sec.
RESET SEQUENCE > push ESC or close the RESET contact for 5 secs. until the beginning of a new cycle.
N.B. These functions exist only in OVER situation. During the normal use of TOP unit, the ESC function
does not work. Instead the RESET contact works only during a single cyle and not during a complete
sequence. See also RESET on SIGNALS I/O.
