blocking the path of the badge or failure of the badge sensor. This error may be corrected by following the
troubleshooting suggestions given in B-Type Error General Trouble shooting section.
M0 Errors
An M0 error occurs as the magazine is advancing to the next slot if the timing sensor does not detect a signal
within the specified time limit, even though the specified number of pulses were transferred to the pulse motor.
Causes and troubleshooting guidance for this error are given in M-Type Error General Troubleshooting section.
N-Type Error General Troubleshooting
The Number Code Reader (NCR) consists of several lamps and photosensors that read the identification holes
which are punched into a badge. These N-type errors occur when one of these lamps fails or when there is a lack
of odd parity (odd number of holes punched in each of the two rows of holes on a badge).
N0 Errors
An N0 error occurs when the current of the illuminating lamp array is not over the specified level. This error
interrupts automatic operation. The probable causes of this error are a drop in lamp voltage or filament breakdown
in the lamp. This error may be resolved by checking the lamp voltage and replacing the lamp array board.
N2 Errors
When the number Code Reader does not detect an odd number of holes punched in each of the two rows of
holes on a badge, an N2 error occurs. If an N2 error occurs, a question mark (?) will be printed in column 8 of the
printout and the badge will not be read. Automatic operation will continue until three successive N2 errors occur,
at which time automatic operation is interrupted. The probable causes of this error include a mispunch of the
parity hole in a given row, a decrease in the signal level of the optical array due to a buildup of dust, failure of the
reading circuits, or failure of the sensors. This error may be resolved by connecting the holes to have odd parity,
clean the optical sensor array window, adjust the comparison level, or replace the reading circuits with a new PC
board.
R-Type Error General Troubleshooting
These errors occur when the IRRADIATOR is connected to a computer or smart printer. These transmission
modes may also be selected in "RS232 Options" screen. These two modes of transmission require a partial
"handshake" for the data link mode and a full "handshake" for the basic mode.
R2 Errors
The R2 error occurs only in the Basic mode. This error interrupts automatic operation. The R2 error occurs when
NAK is received or both ACK and NAK were not received within the specified time limit by the automatic request
system after three attempts. This error also occurs when the IRRADIATOR detects the low-level CTS signal during
transmission.
There are several causes for this error that are traceable to the failure of the Computer, the Interconnecting cable, or the
IRRADIATOR.
These errors may be corrected by replacing the cable or checking the communication settings.
