Via terminal control
With terminal control it is possible to change to other parameter sets via the digital
inputs.
- Assign ”select parameter set” to one or two digital input of each
parameter set and ”load parameter set” to one dig. input.
- The assignment of the digital inputs must be the same for all parameter
sets used.
- The controller reads the terminals assigned with ”select parameter set” as
binary code. The input with the lower number is the first input, the input
with the next higher number is the seconde input (e.g. E1 = 1st input, E2
= 2nd input). .

The input with the function ”load parameter set” is signal triggered. Length of the
HIGH pulse: 10 ms...2 s.
1. Address digital inputs assigned to the function ”select parameter set”.
2. Inhibit controller with a LOW signal at terminal 28.
3. Supply a HIGH pulse to the digital input assigned to the function ”load
parameter set”.
4. After loading, C002 indicates the number of the loaded parameter set.
5. Enable controller.
Note!
The RDY message is not indicated for the time the controller needs to select a new
parameter set and can thus not respond to new input signals (LED and terminal
44).
7.8.4.5 Password protection
Use a password (three digit number) to protect your parameter settings from
undenied access. If the password is not entered, the parameter of the standard
code set can only be read but not changed. The parameter of the extended code
set can neither be read nor changed:
1. Enter the password under C094.
2. Set C000 to -0- (”Standard code - read only”).
Code C000 can only be changed after input of the password.
