setra local display model LD330 installation and operating instructions. setra? 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 i nstallation 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. 1 9 pin 15 pin 5 pin c a ble b a y onet d-sub d-sub mini-din molex c onnection wire pin pin pin pin + ex cit a tion red a 4 7 1 2 + output green b 1 2 2 1 output white c 8 12 4 4 ex cit a tion bla ck d 9 5 5 5 c ase gnd drain shell shell shell 3 6 9 pin 15 pin 5 pin c a ble ba y onet d-sub d-sub mini-din molex c onnection wire pin pin pin pin + ex cit a tion red a 4 7 1 2 ex cit a tion bla ck d & b 9 5 4 5 c ase gnd dr ain shell shell shell 3 6 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. 2.1 voltage units 2.2 current units http://
2 3.0 panel-mount 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). figure 1 1.55 39.37 1.73 43.18 1.88 47.8 cut out dimensions ?.15 3.81 1.65 41.9 2.25 57.2 1.00 25.4 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. figure 2
