Note 2) When a digital indicator is attached to the transmitter, make sure that the LCD lamp “ZERO” is ON. After adjustment, the transmitter should be kept energized at about 10 seconds to write the adjustment results into memory.
30 4.3 Span adjustment by the external screw The measuring range for each transmitter is determinated according to its type. Span is changed by the outside screw with the mode setting switch in the housing set at span position. The figure shown below is an example of “Mode setting switch” is attached.
31 4.4 Local adjustment unit with LCD display 1. Outline When local adjustment unit with LCD display (Parts number is *ZZPFCX4-A055) is installed in the FCX-CII transmitter, some functions are available without HHC (Hand Held Communicator). Name of each part in local adjustment unit with LCD display and their functions are indicated below.
32 2.Selection of transmitter adjustment method LOCAL/COMM. Changing switch decides the method of FCX-CII transmitter adjustment. If switch is set to “COMM.” side, adjustment of transmitter is carried out by HHC. This method is explained in instruction manual.
33 3.2 Span adjustment (Change Upper Range Value) The measuring range for each transmitter is determined according to its type. The span is changed by the external adj. screw when the mode setting switch is set at “1” or ”6" position. (1) Set the mode setting switch to “1” or ”6” position.
34 MAINTENANCE 5.1 Periodic inspection In order to ensure the measurement accuracy and long life of the transmitter, it is essential to inspect the transmitter periodically according to the operating conditions. Visual inspection Visually inspect each part of the transmitter for damage, corrosion, etc.
35 5.2 Troubleshooting If an abnormality occurred in the process or transmitter, action should be taken with reference to the table below. If remedy is impossible, contact Fuji Electric’s service department. (1) The manifold valve does not open/close normally.
36 5.3 Replacement of parts If the transmitter requires a replacement part, drain process fluid from the transmitter, disconnect it from the process and carry out replacement in an instrument room. Replace the transmission unit with a spare one in order to determine whether it is the detecting unit or transmission unit which is faulty.
37 Replacing procedure (1) Remove the electronics unit according to “Replacement of electronics unit”. (2) Remove the hex. socket bolts from the electronic housing. Pull the electronics housing straight forward and away from the detecting unit. (3) Replace the detecting unit with a new one of the same type.
38 In case of differential transmitter (code symbol : FKK/FDK) : Bolt Measurement chamber detecting cover O-ring Nut Seal diaphragm Seal tape Seal tape (6) After assembly, carry out a pressure test.
39 1. Replacement of analog indicator Replacing procedure (1) Detach the transmitter cover. (2) Remove the analog indicator. (3) Pull out the connector extending from the analog indicator. (4) Connect the connector of a new analog indicator to the electronics section.
40 Replacing procedure (1) Detach the transmitter cover. (2) Remove two fixing screws which fasten the digital indicator and separate the indicator. (3) Pull out the leading end of the flexible PC board extending from the digital indicator after raising the slider (white knob) in the electronics section.
41 5.4 Adjustment after replacement of unit After completion of the assembly work mentioned above, use the following procedures for adjust- ment and setting.
42 6.1 Installation After unpacking, check the delivered items. This transmitter can be mounted on a pipe or on a wall. Note that the bolts (M8) for wall mounting should be supplied by the customer. 6 Mount the bracket to the transmitter. The bracket should be mounted to the process cover as shown below.
43 Pin plug Remove pin plug fitted to indicator. Attachment Mount the supplied attachment on indicator. Studs Indicator attached to transmission unit side. Remove the transmission unit side cover with window and indicator. Remove the terminal unit side cover.
44 Wiring is sometimes difficult depending on the installation loca- tion. In such a case, it is convenient to carry out the following. Before turning the transmission unit, remove the electronics unit. The transmission unit is secured by 2 hexagonal socket bolts.
45 Hold the hexagonal area of the vent/drain plug with a wrench and remove it by turning slowly. Peel the existing seal tape and wind a new seal type. Then, screw the vent/drain plug into the process connection for changing. Tightening torque: 25N•m (2.
46 6.2 Piping It is generally recognized that there are appropriate positioning relationship between the transmitter and main process piping for accurate measurement to avoid harmful gas or liquid accumulation. General recognizations are; 1- Mount transmitter below main process piping for liquid or steam measurement.
47 Typical examples of piping Flow measurement (in case of gas) Place the transmitter above the differential pres- sure source. Flow measurement (in case of liquid) Place the transmitter below the differential pres- sure source.
48 Pressure measurement (in case of gas) Mount the transmitter above the process pipes to preventing moisture from entering the inside of transmitter. Level measurement (1) In case of wet leg: For mea.
49 Cautions on impulse piping • For liquid, the impulse pipes should have an upward slope of 1/10 or more between the process connection and the transmitter to prevent accumulation of gas, etc.
50 Gas measurement Liquid measurement Steam measurement Upper Upper Lower Within 45 ° upward from vertical direction Within 45 ° downward from horizontal direction Within 45 ° upward from .
51 Typical examples of piping Gas measurement Place the transmitter above the pressure source. Liquid measurement Place the transmitter below the pressure source. Make piping so that gas in the process pipe is not delivered to the transmitter, and incorporate gas reservoirs as required.
52 Typical example of piping Level measurement of open tank Leave the below pressure side of the transmitter open to atmosphere. Level circulation formula LRV = ρ .H 1 URV = ρ . (H 1 +h) LRV = low limit of measurement (0%) URV = high limit of measurement (100%) ρ = measuring liquid density H 1 = Liquid level h = liquid level change 6.
53 It should be noted that leakage of fluid from the wetted parts would affect the performance due to the progress of corrosion. Important Caution of installation • Restriction on H 1 Liquid level is not proportional to the transmitter output at some points inside the seal diaphragm.
54 WIRING (1) Application of a voltage exceeding 60 V DC or 40 V AC (exceeding 32 V DC or 23 V AC when arrester equipped) between “+” and “–” terminals may result in damage to the transmitter. (2) Use a shielded cable for the transmission line where possible.
55 Tighten the terminal screws (M4 x10) to a torque of approximately 1.5 N•m (15 kgf•cm) <11ft- lb> so that the wires will not loosen. After connection, fasten the cover until it does not turn.
56 Note) For communication with HHC, the smart type requires load resistance 250 Ω as minimum. 600 250 0 1533 Operating zone 10.5 16.1 24 45 Power voltage (Vdc) Load resistance ( ) .
