Startup and operation
RES-430 23
The temperature diagnosis function can thus be expli-
citly deactivated during the closing movement of the
sealing jaws, for instance.
9.4.1 Heatup timeout
(as of software revision 100)
The heatup timeout can be parameterized with
step 219 in the Configuration menu ("0" = OFF).
This timeout starts when the START signal is activated.
The RES-430 then monitors the time required for the
ACTUAL temperature to reach 95% of the SET tempe-
rature. If this time is longer than the parameterized
time, the corresponding error code (804) is indicated
(

9.5 Load cell interface /
temperature sensor
9.5.1 General
The RES-430 controller can be connected to a load cell
and a temperature sensor. The load cell is used to
measure the closing force of the heatsealing mecha-
nism. This force can be monitored by the controller
during the heatsealing cycle. If the closing pressure is
outside the specified limit values, the heatsealing cycle
is interrupted and an alarm is indicated on the display.
The temperature sensor can be used to monitor either
the internal machine/equipment temperature or the
temperature of the load cell. An alarm is output by the
controller if the maximum permissible temperature is
exceeded.
The settings for the load cell interface and the tempera-
ture sensor can be selected as follows with step 241 in
the Configuration menu:
1. "OFF" (Factory setting)
Load cell interface and temperature sensor not
active
2. "Force"
Load cell interface for force measurement active,
temperature sensor not active
3. "Temperature"
Temperature sensor active, load cell interface not
active
4. "Temperature and force"
Load cell interface for force measurement and tem-
perature sensor active
The menu steps 242 to 246 described below
are accessible if step 241 is set accordingly.
9.5.2 Force diagnosis
The RES-430 checks during the heatsealing phase
(assuming this has been activated with step 241) whe-
ther the measured force of the connected load cell is
inside a settable tolerance band ("OK window"). The
upper and lower limit values can be changed separa-
tely by means of steps 242+243 in the Configuration
menu.
If the measured force is outside the specified tolerance
during the parameterized monitoring time, the heatse-
