Removing a Channel from a Group:
1. Select the group from which the channel is to be removed by repeatedly
pressing the group key.
2. Touch the channel key repeatedly until the colored frame around the key
and the group letter under the channel symbol disappear. Refer
to Fig. 4‐46.
The channel can now be assigned to another group. Refer to Defining
Groups, Example.
Key Reset
When this key is touched, all groups are dissolved and the channel symbols
are reset. However, the PID parameters remain unchanged.
Standard I/O group inputs
Input: No more than four of the eight possible application groups A to H can
be assigned to the four corresponding inputs of the interface Standard I/O
(Also refer to section Installation).
The desired input for the application group is selected by pressing the key
repeatedly. The inputs 1 to 4 are permanently assigned to the pins 11 to 14
of the interface.
No input: These application groups can not be switched via the interface
Standard I/O. These groups must be switched by the operator via the control
panel or via the field bus.
Selecting Feature
Deactivated: The temperature channels assigned to a deactivated
application group are not heated.
Temperature control and monitoring for faults do not take place. Exception:
Overtemperature shutdown at a fixed temperature value of 245°C (475°F)
with standard melters or 265°C (510°F) with high temperature melters.
Standby: The temperature channels in this application group are lowered by
the standby values set in the temperature parameter screen (Refer to Fig.
4‐26).
