Operating the sequencer
The sequencer has the following functions:
• Programmable sequence with a 16 steps pattern
• Measurement display
• Alarm and limit control
• Analog output control
• Data sent via RS232
• Switch to the next channel (I + 1) in the programmed sequence if:
• the sample of channel I is missing (the warning relay and a message on display are
simultaneously activated until next access of channel I in the programmed sequence).
IMPORTANT: This functionality is not available if coupled with an 8810-ISE analyzer
Remotely inhibit channel I (J2 to J7 contacts)
Remotely acknowledge system alarm (J8 contact)
If all samples are missing (or inhibited), the sequencer stops and the system alarm is activated.
