15. Confirmation of mounting direction of transducer
a. Plates to show X, X’, Y and Y’ directions shall be confirmed
to have been affixed correctly.
b. It shall be confirmed that when a metal plate such as a tab
of a can is attached to one of the transducer surface, the
corresponding image will be changed.
c. This shall be applied to 4 transducers.
16. Operation of limit switches for reaching sea bottom and upper limits
When the sensor is raised up and down, the driving motor shall stop with signals from limit switches.
17. Adjustment of sensor’s lifting speed and lowering speed
a. The winch shall be mounted on a water bath where the sensor could be lifted and descend by 2
m or more.
b. After the “Sensor speed control” knob has been turned fully counterclockwise, the “Sensor
movement control” switch for UP/STOP/DOWN shall be switched over. When the sensor starts
moving, the lifting speed shall be increased.
c. The moving speed shall be set at “STOP” at full counterclockwise position of the “Sensor speed
control” knob and to be “lowering speed of 20 m/min” at full clockwise position. Dead slow
speed at scale “2” shall be also confirmed.
After connecting the frequency meter (with a probe of 10:1) to TP-17 of 7000 PCB, set the
maximum voltage of motor controller to be 33 Hz max at full clockwise position of the lifting and
lowering speed control knob during lowering of the sensor. Neglect the fractional part.
d. Speed adjustment shall be performed by “Motor controller (SP-3) or (DMC-001)” at the rear
panel of recorder unit.
y For DM-602/604, a frequency meter shall be connected to terminal TP-16 of C25-700B PCB.

Minimum voltage adjustment
(Low speed fine adjustment)
Maximum voltage adjustment
(high speed fine adjustment)
When adjustment of high speed cannot be done, the fixed resistance of 1
k
Ω in the controller should be replaced with a resistance of a few k Ω .
This portion shall be kept contacted. The switch shall
be set to be turned off, when this portion is raised by
2 ~ 3 mm. (Sensor will stop descent)
There shall have 2 ~ 3 mm allowance
at the beginning of contact between
the hanger and the switch.
