of the internal time control cannot be started with
this key.
The timeout of the internal time control (timer
function) can be interrupted by switching off
the controller. It can also be interrupted by deacti-
vating the "START" signal if time control "ON with
START monitoring" is configured.
If the display is in the home position, the individual
timeouts can be monitored there.
The remaining heatsealing time is indicated on the dis-
play in the form of a countdown at the end of the hea-
ting phase. A direction arrow indicates the active pro-
cess.
The active cooling phase is subsequently marked with
the direction arrow at the end of the heating phase.
The direction arrow disappears again at the end of the
cooling phase (i.e. at the end of the internal timeout).
The current condition of relay K1 is indicated by means
of a separate icon. If the icon is visible, the normally
open contact of the relay is closed.
Separate settings can be entered for the individual
timeouts. These settings are possible with steps 103,
104 and 105 in the Settings menu and with steps 210
and 212 in the Configuration menu.
The options available with these advanced settings are
described below.
9.23.2 Setting the starting delay
The start of the heating process can be explicitly
delayed by entering a starting delay time with step 103
in the Settings menu, e.g. in order to bridge the closing
time of the heatsealing bars.
When the "START" signal is activated, the controller
waits for the time specified with this menu step to
elapse before commencing the heating process.
