■Definition and terminology
Term
Definition
A Accumulated flow The total amount of fluid that has passed through the device. If an instantaneous
flow of 100 L/min lasts for 5 minutes, the accumulated flow will be 5 x 100 = 500 L.
Accumulated-value hold time
A function to store the cumulative flow value in the product's internal memory at
certain time intervals. Reads the memory data when power is supplied.
Accumulation of data begins with the value read at the moment power is
supplied. The time interval for memorizing can be selected from 2 or 5 minutes.
AMS
Air Management System.
B Base A unit which establishes wireless communication of input or output data to the
remote. It is connected to a PLC to establish communication of input or output data.
Bottom value display (mode) Shows the min. from when the power was supplied to the current time.
Broken line detection A broken wire to the input or output equipment has been detected by the
diagnostic function.
C Chattering The problem of the switch output turning ON and OFF repeatedly around the
set point value at high frequency due to the effect of pulsation.
Current consumption
Current which is necessary to operate each unit.
D
Delay time
•Standby ON Delay
The setting time from when the measured flow rate under standby flow
rate(threshold) to the set duration. If the standby input signal received and
Standby ON Delay time reached, the AMS change to standby mode.
•Standby OFF Delay
The setting time from when the measured flow rate exceeds standby flow
rate(threshold) to the set duration. When the AMS returns to Operation mode,
AMS shall be back to Standby mode without waiting for Standby ON Delay time.
DHCP
A protocol that automatically allocates information, necessary to be registered
to use the network, such as an IP address, to individual devices connected to
the TCP/IP network.
Digital filter
