Setra Local Display

Model LD330

Installation and Operating Instructions.

Setra’s Model LD330 is a small local display designed for convenient

in-line installation. It can be used with voltage output and current output tranducers

4-pin bayonet connectors (which meet dimensional requirements of MIL-C-26482

and the MIL STD 3116) Amp jack, 15 Pin and

9 Pin D-Sub connectors.

1.0 INSTALLATION

The LD330 can be supplied with a variety of integral electrical connectors to connect to the

mating connectors on the transducer. Consult part number chart below to determine the

proper configuration. For setting optimum viewing angle, the LD330 display housing can

rotate, at least 270 degrees, with respect to the connector. DO NOT ATTEMPT TO FORCE

ROTATIONAL ADJUSTMENT BEYOND STOP POSITION.

The LD330 is available in a variety of configurations.

CONFIGURATION

If the panel-mount configuration is

supplied, see Figure 1 for cut-out

dimensions. Insert the panel-mount

display through the front and secure

to the panel with four mounting

screws (not supplied).

4.0 CALIBRATION

The LD330 is factory calibrated to display engineering units. The multi-turn pots on the front

face are for zero and span display adjustment. Setra recommends that the zero adjustments

be done using the transducer zero potentiometer whenever possible. The display zero

potentiometer should only be used for minor adjustments. Never adjust the span potenti-

ometer unless proper calibration equipment is used and proper calibration procedures are

followed.

4.1 Zero & Sensitivity Adjustment

The zero and sensitivity (span) potentiometer are located on the front of the unit just

under the digital display. Remove the protective plugs to access the potentiometers.

1. Apply zero pressure to the transducer and adjust the LD330's zero potentiometer if

the LD330 does not display "0".

Note: For a compound range (eg -14.7 to 100 psig unit) apply "0" psig pressure to

the transducer and adjust the LD330 zero potentiometer until the display is "0". Do

not apply -14.7 psig and attempt to adjust the display to "-14.7".

2. Apply full scale output to the transducer/transmitter and adjust the span potentio-

meter on the LD330 if the LD330 does not display the correct value. If the adjust-

ment seems sensitive verify that the LD330 is the correct range for your transducer.

Repeat steps 1 and 2 as necessary.

4.2 Decimal Points

The LD330 decimal point is factory set to custom specified range. Figure 2 below

shows the jumper settings required for decimal point settings.

To access this jumper, remove the 2 screws on the backside of the

LD330 housing and

remove the back

cover. Remove jumper

if decimal point is not

required.

4.3 Backlighting

The LD330V comes

standard with green

backlighting. LD330C is not

offered with backlighting. To disable backlighting of LD330V, remove the Back Light

Jumper shown in figure below.
