Operation
Page 58/121 Art.-No. 592.016 2008-11-26
Pre-ventilation time
Same function as pre-ventilation pressure, but pre-ventilation only lasts until
the set time elapses instead of up to the set value. (Emergency operation in
the event of defective vacuum probe)
Vacuuming time
Same function as vacuuming to the set point, but vacuuming continues in-
stead of up to the set value only until the set time elapses. (Emergency opera-
tion in the event of defective vacuum probe).
Sealing time
The programmed sealing time starts as soon as the sealing temperature has
been reached. The sealing bars are no longer heated once the sealing time
has expired. The cool down process subsequently begins.
Setting range: 0,0 – 6,0 s
Sealing
on – sealing is switched on
off - sealing is switched off
Sealing temperature
Use test cycles to adjust the sealing temperature to the bag material.
Setting range: 20 °C – 300 °C (68 °F – 572 °F)
Practical value for shrink bags: 90 °C – 130 °C (194 °F – 266 °F)
Cooling temperature
The sealing bars cool down once the sealing period has expired. The upper
sealing bars are raised once the defined cooling temperature has been
reached.
Setting range: 20 °C – 300 °C (68 °F – 572 °F)
Speed conveyor belt
The conveyor belt can be set to one of six possible speeds or completely
switched off (position "0").
Speed stage 0: Conveyor belt is switched off
Speed stage 1: Minimum speed (approx. 0.1 m/s)
Speed stage 6:
Maximum speed (approx. 0.5 m/s)
(Factory setting)
The speed stages 1 to 6 can be preset in the control box at the frequency
converter. See the separate user manual of the frequency converter.
Ramp start / stop
1 steepest ramp, the target speed is achieved quickly
3 slightest ramp, the target speed is achieved slowly
