6.4 Structural Features of Direct system
6.4.1. Description of panel
(1) Fault indicator: yellow. When the external control line of this road is
short-circuited or open-circuited, the light will come on.
(2) Start indicator: red, which lights up after the control command is issued.
(3) Feedback indicator: red. When the controlled equipment is in response to the
command, the feedback indicator lights up.
6.4.2. Description of direct control panel
The structural diagram of the output part of 6.4.2.1 Special Line is shown in Figure
6-1:
Figure 6-1
In which:
Q, G: Start output terminal, and output DC24V when starting. Output current is less
than 200mA, load is signal relay, and coil resistance is 0.5-2K.
H, g: answer signal input terminal of external equipment, which is the answer signal
when passive closing, and the terminal resistance is 4.7K
Wiring requirements of 6.4.2.4: BV copper conductor should be used for wiring of
multi-wire external control points, with cross-sectional area ≥ 1.0mm
