Electrical Specifications - Denison Hydraulics 9-UK-22071-C Manual

Multi-Function Proportional Valve Dual Driver ( Encapsulated )
1) Isolate electric motor drives to the hydraulic pumps.
Initial Dry set-up
2) Ensure that all connections conform with one of the suggested schematic diagrams shown in this manual.
procedure:
3) Check that all connections are secure and NOT shorting together OR to the case OR any other equipment.
4) Ensure that ALL the links needed are fitted and configured to suit the required application, product and available signals.
5) Install a 'Current meter' in line with the 'A' output, set to a relative current range.
6) Make sure that ( If Fitted ) the 'Emergency Stop' switch is closed and connected to correct supply voltage.
6) Apply power ( +12V +/-10% OR +24V +/-20% ) to the unit and ensure that the 'Power On' light is on and bright.
8) Move the joystick or command potentiometer until Approx.. +10% of chosen configured command is achieved.
9) Set 'I Min' A to give Approx.10% of the valve products maximum drive current ( see valve literature ) on the relative meter.
10) Ensure that front panel indicator 'Output A' lights ( Dimly )
11) Move the joystick or command potentiometer until +100% of chosen configured command is achieved.
12) Set 'I Max' A give 100% of the valve products maximum drive current ( see valve literature ) on the relative meter.
13) Ensure that front panel indicator 'Output A' lights ( Brightly ).
14) Repeat steps 8) throe 13) until required Min & Max currents are reached for +10% and +100% command signal input.
15) Open 'Emergency Stop' switch and check that:-
16) Set command signal to zero position.
17) Reset 'Emergency Stop' switch to closed position and ensure that 'Emergency Stop' Indicator light goes OUT.
18) Repeat steps 8) thro 17) using -10% and -100% command signal values and moving the current meter to the 'B' output.
1) Ensure that ALL moving parts are guarded and personnel are aware of a 'LIVE' system run.
Final 'Live'
2) Ensure joystick or command potentiometer is at zero position with zero % command output.
calibration
3) Start hydraulic power pack and wait until constant speed / set pressure has been achieved.
procedure
4) Move the joystick or command potentiometer SLOWLY until Approx. +10% of chosen configured command is achieved.
5) Monitor hydraulic product being controlled and set 'I Min' A to give desired minimum flow or pressure.
6) Move the joystick or command potentiometer SLOWLY until +100% of chosen configured command is achieved.
7) Monitor hydraulic product being controlled and set 'I Max' A to give desired maximum flow or pressure.
8) Repeat steps 4) thro 7) until required minimum and maximum system flows are achieved for +10% and +100% command.
9) Set command signal to zero position.
10) Repeat steps 4) thro 7) using -10% and -100% command signal.
11) Set command signal to zero position.
