WHAT IS THE SRS DC-PWM©?
The System consists of:
•
a Car Door Operator (1)
•
a microprocessor-based Door Controller (2)
•
a DC Motor (3) with feedback signals (4)
•
a 230/115Vac - 24Vac transformer (5)
The "Sematic SRS DC-PWM©" controller automatically controls the opening and closing of the lift doors, monitoring the timing, current
variations, speeds (high speed, low speed), various safety systems (reversing system, etc.) and faults (high voltage, signal failure, ...).
There are two independent speed curve profiles for the opening and closing cycles (6) which can be modified by means of the door
controller regulation trimmers. or by means of the Sematic handset (an optional 8 digit keypad and display accessory which can be
connected to the card by an RJ45 plug).
The handset (7) is a key pad that allows viewing and modification of the function parameters stored in the controller.
It is important to use the Sematic handset for installation or maintenance, as it enables viewing and/or variation of the Encoder
parameters, systems, and operation errors.
Furthermore, it is possible to use the Sematic handset directly from the inside of the car (8).
Making it possible to monitor and modify the door operating parameters from a completely safe position, and also to control the
movement of the coupled car and landing doors during their effective operating cycle.
Warning
: please note that SRS DC-PWM© door controller has a power limitation and is available only with reduced size doors.
If the door installation does not allow the correct operation of the doors, alternative high powered drives are available.
Please contact our sales department.
Note
: the pictures on this document are examples only; real components appearances may differ according to supplied configuration of
door operator and motor.
