Pitagora 4.0 – Timing diagrams


Timing diagrams of the running commands according to the type of system.

Installations with Inverter FUJI LM2
Up direction

Down direction
Hydraulic Lifts – Motor contactors
Direct

(T on) = Contactor’s Time Activation, check on cco feedbacks
(*) Signal feedback for start Valve UP command

Soft Starter

(T on) = Contactor’s Time Activation, check on cco feedbacks
(*) Signal feedback for start Valve UP command
(**) Signal feedback from Soft Starter Deceleration (Soft Stop)


Star Delta

(T on) = Contactor’s Time Activation, check on cco feedbacks
(T on) = Contactor’s Time Disactivation, check on cco feedbacks
(*) Signal feedback for start Valve UP command

Hydro & VVF

(T on) = Contactor’s Time Activation, check on cco feedbacks
(*) Signal feedback for start Valve UP comma
Hydraulic Lifts – Valves controls
Monitor UCM = 30…39 (2 Valves / 3 Valves / BLAIN EV100 / GMV T3010 / MORIS CM 320)

(*) In case of Soft Stop use CV1 for UP Valve’s Contactor
(*) in case of no Soft Stop use CV4 for UP Valve’s Contactor – Tstop = BRK-DIR + 1,5s


3 Valve => No Double Valve Down test (A3 Valve Down couldn’t be present)
3 Valves + A3 => Double Valve Down test

Monitor UCM = 40…44 (GMV NGV)


No Double Valve Down test

Monitor UCM = 45…49 (GMV NGV A3)

(*) Valve commands starts only if RDY signal is active
Note: Motor Contactors Starts Only With RUN Feedback Signal


(*) Valve commands starts only if RDY signal is active

Monitor UCM = 50…59 (BUCHER LRV / BUCHER NTA-2 / BUCHER NTA-2 + DSV A3)


LRV1 + NTA-2 ► No Double Valve Down test (A3 Valve Down couldn’t be present)
LRV1 + NTA-2 + A3 ► Double Valve Down test

Monitor UCM = 60…64 (BUCHER i-VALVE / BUCHER iCON-2)

Monitor of Signal + SMA

Monitor of Signal + SMA

Monitor UCM = 65…74 (START ELEVATOR 93/E-2DS)


(**) Signal feedback from Soft Starter Acceleration (Y-BRKS)
CV1 = Used only with 93/E-SL valves (Soft Stop with delay BRK-DIR)
CV4 = Used only with 93/E-2DS valves (Soft Stop)


3 Valves => No double valve down test (A3 valve down couldn’t be present)
3 valves + A3 => Double valve down test


Monitor UCM = 75…79 (ALGI AZRS 2.0)

(*) BRK-DIR = 0,0 s when “soft STOP” is not requested / BRK-DIR = 0,7 s for “soft STOP”.
