Figure 3: General Configuration Form
Example 1:
Operating Mode (program item 200) is set to 0 (Dynamic Function Selection with
Fault Monitor). Program Selection for Program Block 1 (program item 210) is set to 1 (Pressure
Control) and Program Selection for Program Block 2 (program item 211) is set to 3 (Flow with
Pressure Limit Control). See Figure 3.
If the digital input is low (<5 VDC), Program Block 1 is made active and the active program is
Program 1 (Pressure Control). If the digital input is high (> 5VDC), Program Block 2 is made
active and the active program is Program 3 (Flow with Pressure Limit Control).
Example 2:
Again, operating Mode is set to 0. Program Selection for Program Block 1 (program
item 210) is set to 1 (Pressure Control) and Program Selection for Program Block 2 (program
item 211) is set to 0 (No Program).
If the digital input is low (<5 VDC), Program Block 1 is made active and the active program is
Program 1 (Pressure Control). If the digital input is high (> 5VDC), Program Block 2 is made
active, but since no program is activated, the module uses a special zero function command to
command the pump controller (refer to Section 4.3.2.1 for configuration of the Function Zero
Stroke Command).
Mode 2
: For operating mode 2 (Static Function Selection with Watchdog Daisy Chain) the digital
input is used as a watchdog input signal. Therefore, no dynamic function selection is possible. In
this mode, Program Block 1 is always active and program item 210 defines the active function
program. Program item 211 has no function in operating mode 2.
The program blocks are selected from the General Configuration Form.

After an upload from the EPC to a PC, several non-editable parameters are shown in the General
Configuration Form. These items include the model, serial number, software version and hardware
version. See Figure 3.
