Close pincer jaws from the OPEN position (OF)
The pincer jaws must be open (OF) in order for a closure to be initiated. When a “START” is initiated (depending
on the Start definition: see “START system settings”, p. 8-52) via the Start button or the external X2/X20 interface,
the pincer jaws close to the pre-selected closing gap (SS), provided that this can be achieved with the maximum
pre-selected closing force. On reaching the closing gap the closing gap holding time (SS-HZ) begins.
INFO
Once the preset closing force (SK) is reached, the pincer jaws do not close any further.
Immediately before the end of the closing gap holding time (SS-HZ) the system checks that the closing gap is within
the closing gap tolerance (±SS-T) and that the closing force is within the closing force tolerance (±SK-T). The pincer
jaws are then opened. When the pincer jaws are fully open (OF) the message OK or NO is output (depending on
the OK/NO definition: see “System settings for the OK signal”, p. 8-55 and “System settings for the NO signal”,
p. 8-60).
Close pincer jaws from the OPENING GAP position (OS)
The pincer jaws must be in the opening gap position (OS) within the opening gap tolerance (±OS-T) in order for a
closure to be initiated.
When a “START” is initiated (depending on the Start definition: see “START system settings”, p. 8-52) via the Start
button or the external X2/X20 interface, the pincer jaws close and establish the pre-selected closing gap (SS). On
reaching the closing gap the closing gap holding time (SS-HZ) begins.
Immediately before the end of the closing gap holding time (SS-HZ) the system checks that the closing gap is within
the closing gap tolerance (±SS-T) and that the closing force is within the closing force tolerance (±SK-T).
The pincer jaws are then opened. On reaching the opening gap (OS) within the closing gap tolerance the message
OK or NO is output (depending on the OK/NO definition: see “System settings for the OK signal”, p. 8-55 and
“System settings for the NO signal”, p. 8-60).
INFO
•
On completion of the closure the pincer jaws open fully (OF) and then close again as far as the opening
gap position (OS).
•
The larger the opening gap (OS) that is selected, the less accurate is the opening gap position, as it is
physically not possible to control very low pressures under the influence of friction.
