Table 6.3 Fault codes for AL55/66 coin selectors
Inductive sensor numbers are:
01
Upper inductive sensor
02
First lower inductive sensor
03
Second lower inductive sensor
Message format is:
Host sends:
[Dir] [00] [01] [E8] [Chk]
Coin s. respond:
[01] [01/02] [Dir] [Fault c.][Data opt.] [Chk]
Example of message string for coin selector(
address 2
) with no fault detected is:
Host sends:
[02] [00] [01] [E8] [15]
Coin s. respond:
[01] [01] [02] [00] [00] [FC]
No fault detected
Example of message string for coin selector(
address 2
) with first lower sensor fault
detected is:
Host sends:
[02] [00] [01] [E8] [15]
Coin s. respond:
[01] [02] [02] [00] [02][02] [F7]
Fault on first lower sensor detected
6.5.2.10 Command 231 [hexE7], Modify inhibit status
With this command host is able to inhibit the acceptance of some or all coins.
Acceptance or inhibition is set with a two byte mask sent by host.
Bits from 0 do 15 determinate coin positions from 1 to 16
36
.
Number of coin channels in new ALBERICI coin selectors AL55/66 is same as number of
position(
16
). Message format is:
Host sends:
[Dir] [02] [01] [E7] [LSB Mask.] [MSB Mask.] [Chk]
Coin s. respond:
[01] [00] [Dir] [00] [Chk]
ACK
