9.23.5 Setting the cooling value
After the cooling phase has been configured with
step 210 in the Configuration menu (
section 9.23.4
"Setting the cooling mode" on page 40), you can spe-
cify the cooling parameters with step 105 in the Set-
tings menu.
The options available with step 105 in the
Settings menu vary according to the selec-
tion made with step 210 in the Configuration menu.
All settings entered with menu step 105 are over-
written 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 speci-
fied with step 206 in the Configuration menu or by
the heatsealing band type/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 per-
centage 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 9.99s.
The factory setting is 1.00s.
9.23.6 Relay K1 (with time control)
The function of relay K1 when time control is active is
also specified with step 212 in the Configuration menu
(
section 8.3.7 "Relay K1 (without time control)" on
page 19). The settings described here are only pos-
sible if time control is active. These settings can be
selected as follows:
1.
„OFF“
Relay K1 without function
2.
"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).
3.
"When temperature reached"
(Factory setting)
The normally open contact of relay K1 closes when
the ACTUAL temperature reaches 95% of the SET
temperature and remains closed until the end of the
parameterized timeout (i.e. until the end of the
cooling phase).
4.
"While cooling"
The normally open contact of relay K1 closes at the
end of the heating phase and opens again at the
end of the cooling phase.
This configuration permits air cooling to be activated
with relay K1 during the cooling phase, for instance.
5.
"End-of-cycle impulse"
The normally open contact of relay K1 closes at the
end of the parameterized timeout (i.e. at the end of
the cooling phase) and opens again after approxi-
mately 500ms. If a "START" signal is activated while
relay K1 is still closed, the relay opens again imme-
diately.
