INPUT REGISTER 08: Clear Active Alarm
The Clear Active Alarm register is used to acknowledge an alarm remotely so that the system may resume operation. Be sure that the alarm condition has been alleviated. Write a 1 to this register to acknowledge the latest active alarm. If more than one alarm is currently active only the most recent alarm will be acknowledged. A repeated write should be performed to clear any remaining active alarms. See figure 9.
(See System Errors, page 88 for more information on clearing alarms.)
NOTE: This register is not polled by the ProMix PD2K. An alarm is cleared only when a value of ‘1’ is written to this register. It is recommended that the automation reset this register by writing a 0 to it at all other times to avoid inadvertently clearing an alarm.
INPUT REGISTER 09: Job Complete
The Job Complete register is used to log the current job remotely. Write a ‘1’ to the register to command the ProMix PD2K to flag a job complete.
INPUT REGISTER 10: Gun 1 Trigger
The Gun 1 Trigger register is used to signal the ProMix PD2K when the automatic spray device is triggered. This signal should be sent any time the spray device is triggered. The state of this register provides timing for alarm functions and also drives the flow control algorithm.
NOTE: If enabled, it is imperative that this signal be sent any time the spray device is triggered. Without it the flow control features will not work.
•Write a value of ‘1’ to signal that the gun is triggered.
•Write a value of ‘0’ to signal that the gun is NOT triggered.
NOTE: This register is used only if the Gun Trigger is set to ‘Network’ via System Screen 5 on the ADM. If it is set to ‘Discrete’ this register is ignored and gun trigger is handled via the discrete input. See Digital Inputs, page 25. NOTE: Because timing is so critical for flow control Graco recommends that users provide a discrete input to minimize latency effects.
(See Usage Screen, page 64 for more information on Job Logs and Job Complete.)
NOTE: This register is not polled by the ProMix PD2K. A job is logged only when a value of ‘1’ is written to this register. It is recommended the automation reset this register by writing a 0 to it at all other times to avoid inadvertently logging a job.
