.
Note:
The screen is unilaterally linked to the control by the plug casing.
CAUTION
The BE-8 should be connected to the PMC-2 only in tension-free state.
To activate the BE-8, the parameter P0.21 COM2_application or P0.26 COM1_application must be
set to BE-8.
Note:
• Changes in the parameter P0.21 (or P0.26) are not taken over until after RESET at the PMC-2.
• If BE-8 was selected in the parameter P0.21 (or P0.26), also the PMC-2 expects that a BE-8 is
connected. Otherwise the warning E587 ”BE-Timeout” is triggered.
• If you still get no display in the BE-8, you have probably not yet defined any variables (parameter
group 6 -> see 2.6.3 Variable menu).
