The electronic control system VTA971 is
applied to the substitution of relay control systems in the
switchboards and the renovating panels of contemporary
traction and hydraulic lifts.
The system is easy to use for
the servicing organizations which modernize the relay devices
and at the same time open the way for the progressive
reconstruction of the lift equipment.
The operating system is in accordance
with contemporary legal requests and standards - ČSN EN
81-1, ČSN EN 81-2, ČSN EN 12015 and ČSN 12016.
Basic versions:
- 20 stages of single speed lift with the inductor sensor
of VRN type;
- 18 stages of two-speed lift with inductor sensors of RND
or RJD type;
- 15 stages of single speed lift with stage switches
of VKR40 type;
- 14 stages of two-speed lift with stage switches of
SP40A, SP40B or SP40C type.
In these cases our company offers
the control systems from simple control to Simplex, Poloduplex,
Polotriplex, revision course, driving and the like.
Advantages:
- General use of the system – the system parameters can be
set to control all the basic technologies.
- System can control the four types of the inverter
alternatively (Unidrive SP, .Frenic G11S, Varispeed V7,
Varispeed L7).
- System implements controlling of the hydraulic lift
drives.
- Communication of 2 or 3 systems is supported, which
reduces the power consumption.
- Various automatic door types can be controlled.
- Confirmation of cage and external pre-selections is
implemented.
- System enables the installation of the voice location
indicator according to the EN CSN 81-70, l.5.4.4.2 standard,
-
Light indication of
the important states of lift mechanics, lift car overloading,
output overloading.
-
Control unit can easily be exchanged with
the help of jack leads.
-
Parameter setting enables the fixed and/or
switched cage floor selection.
-
System integrates the Remote Monitoring.
It means, the diagnostic data, supporting the service of the
lift, is stored in the VTA 971 system non-volatile memory, e.g.
the number of rides, the error history etc. The data stored
can be printed out of the memory on the service technician
request and/or can be sent to the service centre using the
data transmission via Internet – LAN network (Ethernet) or
GPRS.
-
The automatic car landing at a selected
stage after a period of inactivity can be set.
-
The polarity of the location sensors can
be set.
-
Gong can be installed for the signalling
of the car overloaded, signalling of an external request to
the lift driving person and/or signalling of the landing at
the pre-selected final stage.
-
Driving of the lift by the lift driving
person is enabled.
-
Lift can be controlled using the buttons
placed on the control system unit.
-
The emergency course for the high
capacity lifts is implemented.
-
Easy operation.
