The possible settings are as follows:
1.
"Cooling temp. in °C"
(if setting with menu step 27 = "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 23 in the Configuration menu or
by the heatsealing band type/temperature range set
with step 22.
2.
"Cooling temp. in %"
(if setting with menu step 27 = "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 27 = "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.
10.19.6 Setting the start of the heatsealing
time
The condition for the start of the set heatsealing time
(step 4 in the Settings menu) can be specified with
step 28 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 (
!
Settings menu,
step 3).
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 (
!
Settings menu,
step 3). The specified heatsealing time does not
start, however, until the ACTUAL temperature of the
heatsealing band reaches 95% of the SET
temperature.
These two alternatives are shown below:
10.19.7 Relay K1 (with time control)
The function of relay K1 when time control is active is
also specified with step 29 in the Configuration menu
(
!
Kap. 9.3.6 „Relay K1 (without time control)“ auf
The settings described here are only possible if time
control is active. These settings can be selected as
follows:
1.
"When start signal present"
The normally open contact of relay K1 closes as
soon as the "START" signal is activated and
remains closed until the end of the parameterized
timeout (i.e. until the end of the cooling phase).
