1.4. Operation
Operation of the CSP-N is similar to previous versions of the CSP.
Installation check-list:-
a) The sound source (boomer plate or sparker) has been connected and that it is in the water.
b) A key pulse is connected – either through the front panel BNC connector or through the
remote input.
c) A good earth has been connected from the ‘Safety Earth’ bolt on the front panel preferably
to both the ship and a sea earth.
d) AC mains is connected to the ‘Mains Input’ connector.
e) 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.
Once switched on, the ‘HV OFF / RESET’ button must be pressed to reset any fault latches and
the light behind the ‘Manual Key’ button is flashing in sequence with the key input signal. The
output power can now be selected by using the two rotary
switches as shown in the accompanying photographs. The two
switches select a combination of capacitor settings (labelled 1 –
12) and voltage settings (labelled LO and HI) so the operator can
choose the power setting required for the job in hand. Please see
next section. Once the appropriate setting has been made, the ‘HV
ON’ button can be pressed whilst simultaneously turning the ‘HV
Enable’ keyswitch clockwise.
A series of up to 5 clicks will be heard depending on the energy
selected as the relays switch in circuit. Once these relays have
engaged, the high voltage is enabled.
If either of the power level switches is moved or if the HV off/reset
button is pressed, the unit will shut down safely. In an emergency,
the red ‘STOP’ button can be pressed.
The maximum repetition rate is governed by the charge rate (2000
Joules per second peak) and the amount of capacitance selected.
For example, at 300J / shot the CSP-N will run at a max of 6 PPS.
