Alarms

6 -1

Chapter 6 Alarms

The SRCP/SRCD series controllers turns off the alarm output (ALM) when an error is

detected.

To cancel the alarm:

■ Turn the power off and then on again.

■ Apply the alarm reset input (RESET) for at least the specified period of time.

(Note that some alarms can only be canceled by turning the power off and then on again.)

* Canceling the alarm while servo-on input (SERVO) is on is dangerous, as it allows the

servo to turn on immediately. First turn the servo OFF and then cancel the alarm after

checking that conditions are safe.

6-1 Checking the alarm

When an alarm occurs, check its status using the following method.

■ Alarm history

The SRCP/SRCD series stores data on the last 100 alarms that occurred. To check this

alarm history on the TPB, see the "13-4 Viewing alarm history" in the SRCP controller

user's manual.

* When an alarm that requires the power to be turned on again occurs, an alarm message

appears along with an alarm buzzer after connecting the TPB.

■ Status LED indication

The LED on the front panel indicated the controller status.
