7.6 Troubleshooting
7.6.1 Indication of "STATUS" LED (red flash)
A safety function operates, and the "STATUS" LED flashes in red when an abnormality/error occurs
while the STP pump is in operation. In the case of the I/O Remote interface, a failure signal also
simultaneously outputs from the "X4 REMOTE" connector.
If an abnormality/error is found, take measures in accordance with Table 37 to Table 43. DO NOT
perform operations not mentioned in Table 37 to Table 43.
Note: The STP-Link (optional accessory) or the display unit iDT-002 (optional accessory) display
an error as a message. Also, the errors being detected can be read via serial communication.
