Contactor switching and Drive-diagram of hydraulic elevators
In principle three pre-signals are sufficient for the hydraulic elevator control, because with the direc-
tions also the slow speed V0 is published.

B30 – Hydraulic – Drives
PARAMETER: START
In this parameter, you can choose two values, namely “Star/ Delta“ and “ Softstart”.
PARAMETER: S/D-REVERSE TIME
This parameter represents the reverse time between star-protection and triangle-protection. The
standard value is 2 seconds.
PARAMETER: COMMAND UP DELAYED ON
If you activate this parameter, you can switch on the up-command with a delay-time. The standard value
is 100 ms. You need this function in connection with Bucher-LRV-Regelkarten.
PARAMETER: DIRECTION UP DELAYED
The parameter has a option to switch on retarded the up direction. The standart value is NO.
PARAMETER: COMMAND UP DELAYED
If you activate this parameter, you can switch off the up-command with a delay-time. The standard value
is 400 ms.
PARAMETER: START WITH DOOR CONTROLLING
If you activate the parameter, you can start the hydraulic-pump in the same time how the motion to close
the door begins. In the standard-parameter set the function is not activated.
PARAMETER: INSPECTION SPEED
The are 3 possiblities:
1.) SPEED SLOW
2.) SPEED Vins
3.) SPEED HIGH
PARAMETER: TIME TO GO DOWN
The hydraulic elevator must lower late after first of all 15 minutes to the lowest stop place. The time is
adjustable by this parameter.
PARAMETER: FAULT HANDLING
By the menu attitude can be selected, as the control has to react to error messages of the regulation.
a. “NO”- regulation does not have a disturbance exit.
b. “STOP + LOWERING”- If there is an error in the regulation, the driving instructions are
taken back and the calls are deleted. The car is lowered into the lowest stop place.
PARAMETER: TRAVEL DOWN AT OVERLOAD
Is overload in the car it must be decided at expiration of the sinking time whether lower or not. The
standart value is NO.
PARAMETER: SIGNAL TOP OF RAMP
After reaching „the Top Of the Ramp“ on the softstart unit approach equipment this further announced
to the regulation. During the attitude of kind of condition this parameter is active.
PARAMTER: COMMAND DOWN DELAYED ON/OFF
The parameter contains the alternative to switch strainghtening on retarded. This is needed with the
employment of a return flow prevention valve ( e.g.ALGI-S5). The standard value is NO.
PARAMETER: DETENT END SWITCH TOP
In this parameter you can choose, if the elevator blocks after leaving upper end switcher and the follow-
ing emergency sinking. Default value is YES.
