recording range. Number of alarm points can optionally be set up to 4 points per channel, and the kinds of alarms
(higher-limit alarm or lower-limit alarm) can be set optionally.
※
) Alarm outputs are prepared up to 36 points max. per unit as option measures.
1. Display and printing of the occurrence and cancellation of alarms
When an alarm occurs, [ALARM] and [CH No.] where an alarm occurred light in the display section. [CH No.] is
displayed by sequentially switching all generated [CH No.]. [Tag], [Kinds of alarms], [Alarm level], and [Alarm
occurrence time] of the channel where an alarm occurred are printed at the right end of the chart, while [Tag],
[Alarm level], and [Alarm cancellation time] are printed when the alarm was canceled.
For analog recording in a channel where an alarm occurred, generation mark __, red under score/cancellation
mark __, and green under score are marked.
(Caution 1)
Alarm occurrence and cancellation printing is related with the chart speed. Be careful with the following items.
①
When the chart speed is lower than 200mm/H, an alarm occurrence is printed red, and an alarm cancellation
is printed green. When the chart speed is higher than 200mm/H, an alarm is printed black, except for the
occurrence and cancellation marks.
②
When the alarm occurrence or cancellation is printed, a printing space is secured for avoiding overlapped
printing, so that the following printing is not done.
(Caution 2)
Max. 120 occurred and cancelled alarms can be stored into memory. Alarm occurrence and cancellation printing
newly occurred during this period is not accumulated.
