(See the block diagram of
frequencies selector)
Constraint START / STOP by
means of RS only when:
- Enable RS (PCH.40) = 1
(about value PCH.40
determine par. 4.7)
- BIT6 of register 2000
(MODBUS) = 1
No RS constraint
BLOCKING
- If fault has done
- Electric drive operates low F STOP (par. 2.13 and 2.14)
- External blocking of operates (par. 2.111)
- External operation permitted to operate (par.210)
- Blocking with RS (Bits 14, 13, 12 of register 2000
MODBUS, when par. 2.60 allow operation RS)
- Blocking from control of pump group.
START (PCH.37)
