The operating mode can be identified and output externally as an event.
The output ON delay time can also be programmed. However, the delay cannot be set to
totalization pulse output. In addition, the output logic can be reversed (during normal operation:
ON; at event occurrence: OFF). However, the output is always OFF when power is off.
‘OK’ LAMP LIGHTING/OUTPUT
The ‘ OK ’ lamp can be made to light when the controlled flow rate is within the “setting value ±
allowable range”. This function is beneficial for visual verification whether or not the new setting
value is being followed properly when a setting value is changed. The ‘
OK ’ lamp output can also
be used as an interlock signal for subsequent processes by assigning it to an event output and
loading it to a sequence program.
AUTOMATIC SHUT-OFF FUNCTION
The valve can be automatically closed under the following conditions:
When the totalization count value reaches the setting value.
When one of the alarms, including flow rate alarms, occurs.
Please note the control valve in the MPC Series Panel Mount MFC does not offer positive shut-
off. If positive shut-off is a system requirement, install a separate shut-off valve.
AUTOMATIC RESET OF TOTALIZATION COUNT AT START OF CONTROL FUNCTION
Start of control and totalization count reset can be carried out simultaneously by a single action
(key operation or external switching input). Combining this function with the automatic shut-off
function described above is handy for shutting the valve off when a fixed number of totalization
values have been counted repeatedly.
DIRECT SETUP FUNCTION
Allows users to easily change the flow rate setup. This function is useful when you frequently
change setting values, for example, when you adjust the preset flow rate during trial operation.
LOADER COMMUNICATION FUNCTION
The connection of a dedicated loader cable (available separately) to the loader jack on the rear of
the MFC enables direct communication with a personal computer in the form of one-to-one using
the user-supplied communication program. By using this loader communication, various settings
in the function setup and the flow rate setup can be configured from a personal computer. The
controlled flow rate or alarm status can be observed with the personal computer.
