Setra LD 330 Operating Manual

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.

2.0 ELECTRICAL CONNECTIONS

The LD330 can be supplied with different style connectors to the input transducer and to
the power supply. The power supply can be supplied with cable, also. Confirm the electrical
connection supplied , and refer to the appropriate column below for
proper connections.

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 potenti­ometer 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 potentio­meter 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.
