15. Diagnostics (power-up)
The SR3 performs a self-test at power-up. If a fault condition is detected and diagnostics is
enabled, an Alarm is activated and the SR3 is inhibited. If the fault condition clears, say a coin
blockage of the credit sensor, the inhibit will be lifted and the SR3 is then ready for normal
operation. A diagnostics test failure is indicated in parallel mode in exactly the same way as an
alarm.
The faults which are detected at power up are:-
¾
Credit sensor blocked.
¾
EEPROM checksum error.
¾
Blockage in the discrimination area.
¾
Sensor faulty.
16. Sorter Option
The SR3 can drive an external 5/6-way sorter. The SR3 and sorter attach to a new style
frontplate. The coin exit positions from the sorter are identical to an industry standard OEM
product. There are two operating modes for use with sorters. One mode is selected during the
setup process.
16.1 Sorter Mode 1 (default)
The SR3 provides a logic signal to enable the sorter solenoids to be driven. The signal is
active for 500ms and generated at the same time as the accept gate is activated There is no
feedback from the sorter.
16.2 Sorter Mode 2
As soon as a coin is discriminated as true, its corresponding credit code is output for 1ms,
after which the accept gate and sorter solenoids are activated. [provided Inhibit All is
inactive].
If the Inhibit All is active (i.e. all coins inhibited), then the credit code is output for 10ms. No
accept gate solenoid activity occurs and the coin is rejected. If during the first 9ms of the
10ms credit pulse, the Inhibit All changes to inactive (i.e. accept), then the coin will be
accepted. The accept gate then operates and the coin accepts. A 100ms credit is issued as
the coin passes the credit sensor.
The host machine drives the sorter solenoids in this application.
16.3 Sorter Mode 3
The issue of the ‘early’ 1ms credit is delayed by a fixed time from completion of coin
discrimination
(TBD).
Provided the Inhibit All line is inactive when the coin completes
discrimination, the coin accepts. The early credit pulse is issued after the fixed delay,
followed by the standard credit pulse of 100ms duration as the coin passes the credit sensor.
Note: Sorter modes 1, 2 & 3 are mutually exclusive. One must be selected when ordering.
