2. LC100 boards description
2.1 LC100-C main control unit
LC100-C is a central control system plate of a LC100 system. In addition to processing input and
output information management and storage system parameters, plate has the function of
communication between peripheral I / O plate system. Communication between different parts of the system is
based on CAN communication. The system has two independent CAN channels. One is
used for CAN communication with the boards on the level of simplex and the other for connection of the landing
call boards for multiplex and the communication to the monitoring system.
Input Power for the system (XC13) is 24 VDC. Voltage tolerance is +10 / -20%. To operate the processor power is
converted through a DC / DC converter to the 5V. Input voltage (24 VDC) is
transmitted directly to the connectors XC1 to XC4, the power is connected across a diode to the XC12 connector for
connecting a landing call boards in multiplex operation. All connectors are different colours and pitches.
Main functions:
- 2 independent CAN bus.
- 14 programmable optocoupler inputs with status LED indicators.
- 6 opt coupler inputs for connecting the LC100-S safety circuit board.
- 8 programmable digital outputs.
- Input for connection of an inductive sensor (NPN) that is used in certain types of copying the position of the
cabin.
- Analog input for PTC probe resistance measurement with adjustable resistance tripping.
- Real-time clock with battery supply.
- Measurement of ambient temperature with adjustable temperature range operation.
.
Pin: 2 on the input connector XC8 is used for connection of PTC sensor and has the ability to customize the level
of tripping over the parameter I-01 and I-02.
Pin XC7: 1 on the connector is for connecting an inductive sensor type NPN to copy elevator position.
All digital inputs are optocoupler with LED status indication of input.
Board is equipped with CR1220-C1 3V battery for storing parameters and statistics.
All inputs and outputs than XC7.1 (inductive) and XC8.2 (PTC probe) are programmable
The example in Figure 1 shows a way of connecting the inputs on the LC100-C plate, the
polarity configuration inputs (NO or NC) is available on all inputs through the configuration parameters TYPE-N.
