The various cooling modes are shown below:
9.3.5
Setting the cooling value
After the cooling phase has been configured with
step 210 in the Configuration menu (
ª
"Setting the cooling mode" on page 19), you can
specify the cooling parameters with step 105 in the
Settings menu.
The options available with step 105 in the
Settings menu vary according to the
selection made with step 210 in the Configuration
menu. All settings entered with menu step 105 are
overwritten if step 210 is changed subsequently.
The possible settings are as follows:
1.
"Cooling temp. in °C"
(if setting with menu step 210 = "Absolute")
The cooling phase of the internal timeout ends when
the ACTUAL temperature of the heatsealing band
falls below the SET temperature.
The minimum settable temperature is 50°C. This is
also the factory setting.
The maximum value of the setting range is
limited either by the maximum value
specified with step 206 in the Configuration menu
or by the temperature range set with step 205.
2.
"Cooling temp. in %"
(if setting with menu step 210 = "Relative")
The cooling phase of the internal timeout ends when
the ACTUAL temperature falls to the specified
percentage of the SET temperature. This value can
be set between 40 and 100%.
The factory setting is 40%.
3.
"Cooling time in s"
(if setting with menu step 210 = "Time")
The cooling phase ends when the specified time
elapses. This time can be set between 0 and 99.9s.
The factory setting is 10.0s.
9.3.6
Setting the start of the heatsealing
time
The start condition for the set heatsealing time
(step 104 in the Settings menu) can be specified with
step 211 in the Configuration menu.
The following settings are possible:
1.
"When heating starts"
The parameterized heatsealing time starts as soon
as the set starting delay elapses (
ª
Settings menu,
step 103).
If the starting delay = 0s, the heatsealing time
begins as soon as the "START" signal is activated.
2.
"When temperature reached"
(•)
Once again, the heating process starts as soon as
the set starting delay elapses (
ª
Settings menu,
step 103). The specified heatsealing time does not
start, however, until the ACTUAL temperature of the
heatsealing band reaches 95% of the SET
temperature.
