V565

High Performance Loop-Powered LCD Indicator

Provides a 3-1/2 Digit LCD Indication with a 1 Volt Loop Drop

 Loop Drop of Only 1 Volt Provides Extra Compliance
 Selectable Square Root Mode for Flow Applications
 LCD Readable from 30ft.
 Switch Selectable 4-20mA, 10-50mA, Decimal Point

and Direct/Reverse "Display Gain"

Description

The V565 is a loop-powered digital process indicator which derives
its power entirely from the 4-20mA or 10-50mA signal being
measured. No local power is required at the point of measurement.

The 3-1/2 digit, 0.8" high Liquid Crystal Display (LCD) provides
clear visibility up to a distance of 30 feet, and can be easily
calibrated to the required range. Zero and fullscale can be set
anywhere between -1999 and 1999. Span can be from 0 to 3998
counts (100 count minimum span).

The V565 provides linear and square root operation, permitting
direct flow readings from differential pressure origins (e.g., orifice
plates). The V565 is also equipped with selectable direct/reverse
display gain. Reverse operation provides a decreasing count with
an increasing input. A trailing, dummy, zero allows display readings
to ±19990. The decimal point position is switch selectable and can
be independently set to any of four positions (1.9.9.9.).

Application

The V565 is useful in any application requiring a wide-ranging 3½
digit display from a 4-20mA or 10-50mA current source. The

enclosure constructed for either indoor or outdoor use to provide
a degree of protection to personnel against access to hazardous
parts; electronics inside the enclosure against ingress of solid
foreign objects; harmful effects on the electronics due to the
ingress of water (rain, sleet, snow); and the external mechanism(s)
remain operable when ice laden. The V565 is ideal for displaying
process variables in local and remote areas where line power is not
available or impractical.

The V565 is entity approved by FM for intrinsically safe operation
in Class I, II, and III, Division 1 & 2 hazardous locations when
installed per manufacturer's drawing 790-0029-00.

The V565 is also intrinsically safe per CSA for operation with the
following housings when installed per manufacturers drawing
790-0025-00: panel housing: Class I, Groups A, B, C and D; conduit
housing: (Opt C) Class I, Groups A, B, C and D. Class II, Groups E,

F and G. Class II, Groups E, F and G.t.

 FM and CSA Safety Approval for Hazardous Installations

 Wide-Ranging 3-1/2 Digit Display

Loop Drop of 1 Volt

The supply requirement of model V565 is only 1.0 volt on a 4­20mA current loop. This is beneficial in applications where
intrinsic safety barriers are used and voltage compliance is at a

premium. The V565 can provide an extra 3-5 volts of loop drive
above standard loop-powered indicators.

Transpak T700 series 2-wire transmitter, includes external
mounting bracket.

U Urethane coating of internal circuitry for additional

protection from corrosive atmospheres

Display Configuration

The V565 is easily configured using the switches and potentiom­eters on the display board. To configure the unit, refer to the
function switches diagram below.

1. Set jumpers W1 & W2 to "Normal" or "Reverse" for direct or
reverse count, respectively.

2. Set switch S2 for the correct current input: "Linear" for linear
operation and "Square Root" for square root operation.

3. Set switch S1 accordingly to obtain the desired zero and span
count values.

4. Fine tune the display using the "Display Zero" and "Display
Span" trimpots. Use table 1 for square root display configuration.
Display readings calibrated for either 4-20mA or 10-50mA linear
scaling will maintain calibration within 1% if switched to the other
range. If readings are inaccurate, the input amplifiers may require
adjustment. See Factory Calibration.

Note: Span refers to counts from minimum to full-scale input.

Calibration

The V565's input and square root zero amplifiers are pre-calibrated at the factory (4-20mA). For best accuracy, the input amplifiers should
be recalibrated when the square root function is selected or the current input is changed (10-50mA). Perform recalibration at an ambient
temperature of 20-30°C (68-86°F).

1. Connect DVM (-) to "TP0" (gnd) of plug P1 and (+) to "ZERO" and "SQRT" for zero and square root calibration, respectively.

2. Apply 4.000mA or 10.000mA to the input. Set S2-1 accordingly.

3. Adjust the "Input Zero" and "Square Root Zero" potentiometers until the DVM reads 0.000 volts (Zero: ±0.0005V; Sqrt: ±0.001V).
Note that Input zero must be calibrated first.

Remove the DVM leads from P1 before configuring the display or errors may occur.

Function Switches

Example shows the V565 configured for a 4/20mA input range and linear display (switch S2), normal count direction (W1/W2), a span between
2400 and 3998 counts (switches 6&7), and zero between 350 and 1999 counts (switches 8&9).

1. Calibrate the input amplifiers (see Calibration).

2. Set the input to 4.000mA or 10.000mA and trim the Display Zero for the desired minimum display value.

3. Set the input to 20.000mA or 50.000mA and trim the Display Span for the desired maximum display value.

4. Set the input to 25% of span. Verify the display count using the table above. Correct by adjusting the Display Zero and repeating steps 3 & 4 as necessary.

5. Set the input to 1% of span. Verify the display count using the table above.

6. Correct by adjusting the Square Root Zero and repeating steps 3-5 as necessary.

The Conduit-Mount enclosure conveniently
mounts any TransPak two-wire transmitter

within a type 3S-rated housing for on-site
process loop indication.

Mounting Enclosures

The following dimension drawing shows both the panel mount (thin case) and the conduit-mount enclosures. The conduit mount is represented
by a dotted line in the top and side views only. The front and back view dimensions are the same for both enclosures.

Note: panel mount includes an attached gasket surrounding the terminals, providing a seal to the panel and the 1" diameter cutout. Four screws
should be used to ensure a tight, flush fit between the panel and the V565.
