Startup and operation
Version 1
RES-430

The temperature diagnosis function can thus be explicitly 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 temperature. If this time is longer than the parameterized time, the
corresponding error code (804) is indicated (
section 10.21 "Error messages" on page 60)

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 mechanism. 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 temper-
ature 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 temperature 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"
