SPECIAL REQUIREMENTS FOR TAXI INSTALLATION
Demands for distance signal generator
The conditions for the compatibility between the taximeter and the distance signal generator
The distance signal generator output should produce low level by connecting taximeter pulse input
signal to ground. The current in that state must be strong enough to make voltage on pulse input to
go below maximum voltage level specified by manufacturer (Vin,low=3.5 max). The sufficient mar-
ginal for disturbance and setup time for stable voltage level must be also considered. The upper limit
for input frequency of distance pulses is 2 kHz. The minimum value for a constant of distance signal
generator is 500 pulses/km.
Installation and service of device
Installation and service of device is allowed only for educated and authorized service accepted by
device manufacturer. Opening device, braking the sealing or disconnecting cables is allowed only for
authorized service.
Instructions for installation and sealing can be found in enclosed document “Sunit Taximeter
SFDIN1-311121 installation, calibration and sealing instructions”.
