heating phase. A direction arrow indicates the active
process.
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 3, 4
and 5 in the Settings menu and with steps 27, 28 and
29 in the Configuration menu.
The options available with these advanced settings are
described below.
10.19.2 Setting the starting delay
The start of the heating process can be explicitly
delayed by entering a starting delay time with step 3 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.
The starting delay can be set in the range from 0 to
9.9s. A delay of 0s is defined as the factory setting. In
this case, the heating process begins as soon as the
"START" signal is activated.
10.19.3 Setting the heatsealing time
This menu step is used to enter the heatsealing time:
There are two possible ways to set the heatsealing
time:
1. "0…99.9s"
The heatsealing time can be set in the range from 0
to 99.9s. The factory setting is 1.0s.
"EXT"
(This setting is possible as of software revision 013)
The heatsealing time is controlled by the "START"
signal (24VDC signal applied to terminals 3+4 or
contact applied to terminals 2+7). The duration of the
