(5) Life alarm:
This function effects to alarm and notice when accumulated count number becomes beyond the fixed total count
number which was set manually.
Output for solenoid valve and Electro-pneumatic regulator (optional) still keep operating condition, though.
Total count number setting can be executed at setting screen No.9, and also, it is able to reset by manual reset or
reset signal from the externals. After input of reset, Life alarm detection is neglected for 2 minutes. After 2 minutes
past, it detects again if pump is operating condition.
(6) Fast alarm:
This function effects to alarm when pump stroke became abnormally faster than the preset stroke rate for some
reasons. Output for solenoid valve and Electro-pneumatic regulator (optional) still keep operating condition,
though.
Stroke rate setting for criterion of warning shall be executed on setting screen No.10.
If actual operating stroke becomes slower than the fixed stroke, then it resets automatically. Also it is able to reset
by reset signal from manual reset device. After reset signal input, it neglects detection for 2 minutes. After
2minuites, it may start again if it is in alarm condition.
①
Possible to fix a specified flow rate control against the load fluctuation at discharge side.
②
Possible to set flow rate freely.
③ P
ossible to display stroke rate, flow rate and total count number while pump is operating.
④
In case of bellows broken, leak alarm will be output to the externals. Pump stops simultaneously with alarm output.
⑤
Possible to set necessary time set for 1 shot of pump operation. When the time for 1 shot of pump is beyond the
setting time, time up alarm will be output to the externals.
⑥
Possible to set total counts number of pump. When count number for 1 shot of pump is beyond the setting number,
life alarm will be output to the externals.
⑦
Possible to set maximum counts stroke rate. When count number for stroke is beyond the setting number while its
operation, first alarm will be outputting to the externals.
⑧
Possible to set alarm reset for start / stop of pump by signals from the externals.
⑨
Possible to select operation mode of controller from MANU and AUTO.
⑩
In case of proximity switch broken, possible to operate pump by timer mode until proximity switch is replaced.
