APPLICATIONS & FEATURES

Flow Readout Boxes provide operating power supply, operating control, flow setting and flow digital display for the mass flow controller (MFC) and the mass flow meter (MFM). D08 series of Flow Readout Boxes can be connected with D07 series MFC or MFM without any change. And, it can also be used for other models of MFC or MFM.
With mini-style of plastic chassis, due to the small volume, D08-1F, 1FP, 1FM are quite convenient to be installed.
Besides the standard 0~+5V signal, there are 4~20mA or 0~10mA current signals of flow input & output signals.
D08-1F Flow Displayer have functions of flow setting and valves drive, it could be operated together with MFC or MFM.
Besides the same function as D08-1F, D08-1FP Flow Displayer also has function of set point display.
D08-1FM do not have flow setting and valves drive functions, which is ONLY used with MFM.

STRUCTURE INSTRUCTION

±15V Power Supply

Composed by switching modules, the AC power supply has wide input voltage and strong anti-jamming. With over-heat and over load protection, the output voltage ±15VDC has high stability and reliability.

 Nominal Power Supply and Flow Setting

From the +5.00V nominal power supply, the 0~5V voltage output which is adjusted by its set potentiometer can be used for controlling MFCs. Because of the soft-start circuit, the voltage will rise gradually from 0 to +5V for avoiding the overshoot of MFC. The time of soft-start will cost 20 seconds approximately.
4.3 Displayer 3 and 1/2 numbers panel can display the readout from MFC (The maximum value: 1999). Flow rate can be displayed by “SCCM”, “SLM” or “%FS”. Normally, the default flow range and unit of Flow Displayer will be set to the user want to.
If the user cannot give MFC flow specifications, the default will be set as %F.S. The SLM and SCCM LED in the frontal panel will indicate the flow unit. Two LBD off means that flow unit is %FS. The radix point, unit of every channel could be adjusted respectively.

Valve Controller

Valve Controller is used for selecting working status of MFC. When MFC is operated normally, it should be “ValveControl”. If MFC valve need to be full opened, it should be “Purge”. MFC valve will be closed if it is “OFF”. Caution:
This function can be only available for D07 series MFC without any problems. For other MFC products, please do NOT connect “Valve Control” pin.

Zero Potentiometer

“Zero Potentiometer” can only adjust zero in a small range for D07 series MFC/MFM products. It will be useless for other MFC products.

 D08-1FP Setpoint Display Function

1FM have the same function of 1F. 1FM also has function of setpoint display. When the Selection switch is on “Flow display”, the Displayer displays the real flow. When the Selection switch is on “Setpoint display”, the Displayer displays the setpoint value

D08-1F&1FP Connection

The ~220V power supply wire and external signal control terminal of D08-1F&1FP Flow Readout Boxes are showing in figure 5.
Besides providing 0~+5V voltage input and output signals, 1F&1FP also has current input and output signals. It can be converted by the rear of connecting terminals shifts.

Normally, the flow readout box is set as “Internal Set” function (which is showing as figure 10a), when shorting “Set” and “Internal Set”, the “setting potentiometer” of the box will control the MFC.
When “Set” and “Internal Set” connecting terminals is not connected, the box is in the position of “Voltage Set” and “External Set”, users connect 0~+5.00V voltage which it is provided by himself (PC data module converter) to “ Set” and “Signal common” terminals to be the external setting signal to control the MFC (figure 10b). It also external connects a setting converter to function as internal and external setting conversion.
When shorting “Set” and “ Current Set” terminal, showing in figure 10c, the box is in the “Current Setting” position, then the input 4~20mA(or 0~10mA) signals of “ Current Input” will control the MFC.

No matter what is current setting or voltage setting, the box has current output and voltage output. Terminal of “Current Test” is corresponding with “Signal common” output 0~+5V flow signals; terminal of “ Current Output” output 4~20mA(or 0~10mA) flow signals. Whether input and output 4~20mA or 0~10mA, it could depend on users order statements and indicate in the rear of chassis.

OPERATION INSTRUCTION

The operation details of Flow Displayer and MFC(or MFM) connection is referenced in related MFC(or MFM) operation instruction.

Turn On: Connect with power supply, device begin operating (There is no power supply switch of 1F,1FP and 1FM, operates it after external alternating current connecting).

MFC (or MFM) Zero Adjustment: warming up 15 minutes after turning it on, in case of no thru-flow, users could use screwdriver to adjust zero potentiometer of display panel.

There are three phases of valve control switch; it should be positioned in “Valve Control” during its
normal operating (1FM could not be functioned as this).

Flow internal setting signals are adjusted by ten-rounded potentiometer of panel (1FM could not have this function).

Shut Off: disconnected its external alternating current.

PARAMETER SETTING

Flow rate unit indication & range should be based on MFC (or MFM). Normally, we set them before come to the users. If user wants to change them ranges before operating, they can adjust flow range and  unit by related switches and potentiometer after open its overall. The related switch and potentiometer are showing in figure 14.

Flow Unit Change

Radix Point Modifying

Displayed Range Adjustment

Flow range display adjustment includes display effective data and radix point modifying. The radix point modifying can be referenced as 7.3; display effective data modifying should be followed as:

a. Disconnected by power supply, take down the connector and the power wire of MFC/MFM (Take down short wires between “SET” and “Internal Set”), and then open the overall.
b. For 1FM, we need input +5.00V voltage between the terminal “Flow Readout” and “Signal Common” of back panel.
For 1F&1FP, we need short the terminal of “Flow Readout” & “Internal Set” of back panel and turn the setting
potentiometer Clock Wise to maximum (Internal Set output signal is full scale +5.00V)
c. Connecting to power supply, after 20 seconds, for the display value, adjust the potentiometer RP3 (showing in figure 10) by screwdriver to match the same full scale value of bypass (Please be attention, the display data range is 0~1999 of corresponding 3 and 1/2 digital voltage meter and simultaneously matching position of radix point.)
d. Disconnect the power supply, for 1FM, it should be cut off external +5.00V voltage; for 1F&1FP Flow Readout Box, it should be cut off the wire of “Flow Readout” from “ Internal Set”.
e. After mounting its overall, the range adjustment is terminated (resume the short wire of “Set” from “Internal Set”) to normal operation.

CAUTION

Forbidden Item

All internal potentiometers in the device have been already adjusted before delivery, please do NOT adjust it. The maximum 15V power should not be overload.

Flow Range Adjustment

Flow range adjustment should be under controlled or advised by our professional maintainer and customer service staff. It should be especially careful operating while it was open or connected by power.

Fuse Change

D08-1F/1FP/1FM Flow Readout Box power fuse is inside box chassis, in case of no display indicated by power connecting, it could be checked for fuse situation. In this time, it should be loosen the bolt of chassis and lift down the overall to change the fuse.

Grounding Connection

In principle, the ground of the Flow Readout Box (Power GND) and the cover of MFC(or MFM) should be connected for sharing the same grounding place. But they can be connected with the bases respectively, if the connection cable is too long. In this way, please make sure the box must NOT be connected with ground of the MFC because ground wire may be broken, even burning.

Substitution

If the Flow Readout Box is used for other model MFC (or MFM), please make sure the capability of power supply and the correct connections firstly. Especially, please be very careful for the valve control function and connections because it is quite different according to the different models.
