Current Output Isolator; Interconnection; Synchronization - Milltronics HydroRanger I Instruction Manual

Current Output Isolator

The isolator is mounted onto the upper left hand corner of the motherboard using the
two long machine screws provided. It is then interconnected from its input terminals to
the motherboard output terminals, TB-1, using twisted pair maximum 16 ga. wire. Refer
to Figure 2 and 3.
Proper shielding and grounding are required in order to minimize noise levels that could
otherwise affect weak receiver signals by introducing false echoes.
The isolator enclosure is grounded by the mounting bolts to the motherboard. This can
be checked with an ohmmeter if a poor connection is suspected.
THE ISOLATOR OUTPUT WIRING MUST BE A SHIELDED TWISTED PAIR. THE SHIELD MUST BE
INTACT UP TO THE ISOLATOR AND THE SHIELD GROUNDED AT THE ISOLATOR MOUNTING
SCREW ONLY. DO NOT GROUND SHIELD AT ANY OTHER POINT AS THIS WILL VOID ISOLATION.

Interconnection

NOTE: All wiring must be done in conjunction with approved conduit, boxes and
fittings and to procedures in accordance with all governing regulations.
Refer to Figure 2 for wiring of power, analog output, transducer and temperature sensor
to the main electronics.

Synchronization

In applications where more than one HydroRanger I, up to a maximum of 8, are going
to be used or where their transducers will be sharing a common conduit,
synchronization is required. When synchronized no HydroRanger I(s) will transmit
within 180 mSec. of the prior one(s).
To synchronize HydroRanger I's, interconnect the SYNC terminals TB1-4 of all
motherboards and ensure that there is a common hydro ground interconnecting
all units.
To synchronize HydroRanger Is and MultiRanger Plus's interconnect the SYNC
terminals TB1-4 of all motherboards and ensure that there is a common ground
interconnecting all units.
To synchronize HydroRanger I's and MultiRangers, interconnect the SYNC terminal
TB1-4 of the HydroRanger I to the SYNC terminal TB1-9 of the MultiRanger.
To synchronize more than 8 MultiRangers or MultiRangers with other Milltronics
ultrasonic level detection models (e.g. MicroRanger, AiRanger, etc. ...), consult
Milltronics or your distributor.
Refer to Figure 3 for details on synchronization wiring.
