1.1.4
Fully Programmable Operation via LCD Display
The S-80 is fully programmable and incorporates a backlit 2 x 16 character display allowing the user to
configure:
The vertical gate position (88-degree maximum vertical limit).
•
Gate arm ascent and descent times (limited to AREMA recommended ranges)
•
•
Six contact settings to be open or closed in the horizontal position and at what degree the
contact is to change state (for example the gate down (GD) contact would be programmed
to be closed in the horizontal position (0 degrees) and then programmed to open at 5
degrees).
Gate arm retention (enabled or disabled).
•
•
Gate arm length (required for diagnostic capability).
1.1.5
Automated Counterweight Assistant
The automated counterweight assistant (available as part of the Digitalization Package upgrade) helps to
prevent improper adjustment and installation on gates. Once the gate arm length is entered
(programmed) into the gate control board and the preliminary install is complete, the gate is run through
a calibration sequence. This provides step-by-step instructions on how to adjust counterweights, which
ensures optimum adjustment of horizontal and vertical torques.
NO GATE SHOULD EVER BE INSTALLED AND NOT PROPERLY
ADJUSTED.
SIEMENS ASSUMES NO LIABILITY FOR IMPROPER INSTALLATION,
MAINTENANCE, OR OPERATION.
1.2
ADVANCEMENTS
1.2.1
Fully programmable Digital Contacts
There are no mechanical cams and contacts to be adjusted in the S-80. These have been replaced with
six fully programmable digital contacts that are based on Siemens' I/O circuit technology.
There are provisions for six (6) digital contacts that can be used for bell operation, gate position detection
(GP), traffic preemption interfaces, etc. These can be configured to be open or closed in the horizontal
position and programmed to change state, from 1 to 88 degrees, in 1-degree increments.
1.2.2
Operating Mode Switch
This replaces the Gold Nut test link configuration used in previous models. The toggle switch enables the
gate to be put into Maintenance mode, to manually power down the gate in the event of a broken gate
arm, using the Motor Down push button.
