Transmitter adjusting mechanism (Figure 7)
This mechanism consists of two toothed gates 51, 55 with the spring 52 hung in them. The bar with the pins 53 provides
for linear movement of both gates. This assembly can be turned around the pin 54. The entire mechanism is mounted on the
main control board 67
(Figure 2). The toothed gates are engaged with the transmitter pinion 43 (Figure 7) and pinion 49
(Figure 5). Position of pin 54 determines the gear ratio of the setting mechanism – i.e. for various values of working stroke of
actuator and thus also for various turning of cam shaft in signalling unit, the transmitter turning angle and the local position
indicator turning angle is always 160°. This enables the rated transmitter signal value of 100
Ω
to be available for any working
stroke value, i.e. 100
Ω
.
