Transmission Cable Short Detection Function
This function protects the system by detecting the current out of the specifications of the AnyWireASLINK system across DP-
DN or 24V-DP and stopping the transmission.
How to check the transmission cable short status
If the NZ2AW1GNAL is in the following state, a transmission cable short has occurred.
• The ALM LED flashes at 2-second intervals.
• When any of the transmission cables (DP, DN) is short-circuited, DP/DN short error (RX1) turns on.
• When any of the transmission cables (24V, DP) is short-circuited, 24V/DP short error (RX2) turns on.
• DP/DN short error (alarm code: 0CC9H) or 24V/DP short error (alarm code: 0CCBH) is stored in Latest alarm code storage
area (RWr2), and "0FFFH" is stored in Latest alarm ID storage area (RWr3).
*1
• The AnyWireASLINK transmission stops.
*1 If multiple alarms occur simultaneously, the latest alarm is displayed.
How to recover from the transmission cable short status
How to recover from the transmission cable short status is as follows.
1.
Eliminate the short-circuit in the AnyWireASLINK system.
When the short status is cleared, the AnyWireASLINK transmission restarts automatically.
If AnyWireASLINK transmission does not restart, the short-circuit has not been eliminated. Therefore, check the wiring again.
2.
Power off and on the AnyWireASLINK system or turn off and on Error reset request flag (RY0).
The following status is resulted.
• DP/DN short error (RX1) and 24V/DP short error (RX2) turn off.
• The ALM LED turns off.
• The contents of Latest alarm code storage area (RWr2) and Latest alarm ID storage area (RWr3) are cleared.
