OPERATION
Operation of the CSP-S is similar to previous versions of the CSP.
Installation check-list:-
a) System interconnections on rear panel are made.
b) The sound source (boomer plate or sparker) has been connected and that it is in
the water.
c) A key pulse is connected
– either through the front panel BNC connector or
through the remote input.
d)
A good earth has been connected from the ‘Safety Earth’ bolt on the front panel
preferably to both the ship and a sea earth.
e)
AC mains is connected to the ‘Mains Input’ connector.
f) A safety check has been carried out to ensure that there is no-one in the water
and that crew members know that the unit is about to be operated.
Power Up
When suitably connected to ground, the transducer and AC mains, and the transducer is
in the water, the power can be applied using the ON / OFF switch and circuit breaker.
The fans will run, and the HV OFF / RESET button will illuminate. Select the appropriate
power output required and press the RESET button to reset the internal circuitry. Turn
and hold the HV ENABLE KEY & simultaneously press the HV ON button: there will be a
small delay before the HV relays engage, and then the high voltage will come on as
indicated by the illuminated HV ON switch. Any changes in system parameters (such as
power change) will cause the HV to switch OFF, and the unit will need to be RESET
before the HV can be switched on again. If the INTERLOCK indicator illuminates, check
the HV plug / HV junction box.
Trigger Input
Trigger input is by BNC connector. The unit ave trigger (triggers on rising edge)
5 - 20 volts. opto-isolated, or by contact closure, as controlled by the KEY switch. (OUT
for +ve key, IN for contact closure.) The manual key button can be used too and this
also shows, by illumination, when a key pulse has been accepted. (A lockout circuit
limits the unit to around 6PPS maximum.)
Local / Remote
The LOCAL / REMOTE switch allows connection of remote box for operation from the
laboratory or instrument room. Using the remote box is achieved by turning the LOCAL /
REMOTE switch to remote. The high voltage can only be turned on from the instrument
room and
not
from the CSP-D Unit. The high voltage OFF button is operational from the
CSP-D Unit
and
remote box. The CSP Unit can also be keyed from the remote box via a
BNC socket. The remote also monitors the status of the key detect circuitry, and the key
LED will only illuminate on reception of a valid key pulse within the CSP-D itself, thus the
operator can also see if the interconnection cable is OK. The remote also has a FAULT
LED, as well as high voltage ON and high voltage OFF indicators.
LOCAL Operation indicated by LED on
– Switch OUT.
REMOTE Operation indicated by LED out
– switch IN
