1.6 OIL TEMPERATURE TRANSDUCER INST.
Before installing the transducer, twist the red and black leads together,
so there is a twist approximately every ½ inch or so. The transducer is
mounted on the engine and is designed for mounting according to
MS28034-1 for most USA aircraft manufactured engines. Consult your
engine manual for the proper installation location and compatibility. A
gasket is supplied for use with the temperature transducer. Install
transducer before connecting it to the cable. Avoid placing the
transducer and wiring near any transmitter cables or antennas as they
can radiate enough energy to temporarily disturb the readings. Connect
to the DPU harness as shown in ‘APPENDIX B: DPU P1 Connector
Harness Fabrication’.
You may either connect using the supplied terminals or with an
equivalent or better method.
1.7 OIL PRESSURE TRANSDUCER INST.
Using the provided 'Adell' clamp, mount the transducer to a stationary
location, such as the engine mount or firewall, then safety wire it to the
clamp. Insure the safety wire does not contact any wiring on the
transducer. Connect the transducer pressure port using the appropriate
aircraft grade hose and fittings. The transducer has a 1/8 NPT external
thread to accommodate many plumbing options. Use only aircraft grade
fittings and hoses rated for use on this application. Refer to your engine
manual for the proper engine oil pressure port location. Connect to the
DPU harness, using a hirschmann connector, as shown in ‘APPENDIX
B: DPU P1 Connector Harness Fabrication’.
IMPORTANT NOTES:
DO NOT: mount transducer directly on engine.
DO NOT: mount the transducer where corrosive or conductive
fluids may contact it during operation or maintenance. Cover
during any washdown operation.
DO NOT: solder onto terminal lugs of the transducer.
DO NOT: dent or deform the transducer in any way or improper
operation will result
