Product Features
Dip-switch Settings
Switch 3 and 4 sets the ESI-1 Operation Mode. Switch 3 and 4 must be set to OFF. Any other setting is preserved and the ESI-1 will not work as
described in this manual.
Dip-switch no1 can be used to set prioritization of the ESI-1.
Switch no1 OFF (default):
All other devices sending thrust have higher priority over ESI-1. This means that
ESI-1 will send 0% thrust to bow and stern when any other devices are sending
bow or stern thrust. ESI-1 will resume control over thrusters 3 seconds after the
last command from other devices.
Switch no1 ON:
ESI-1 will have the same priority as all other devices. In this case, ESI-1 will always
send thrust with the same priority as other devices. The thruster controller will
output the highest thrust received and stop if signals have conflicting directions.
Connections
ESI-1 needs to be powered externally with 8-31V DC, and S-link connection for communication with thruster controllers. Relay outputs RO1 & RO2
is normally open (NO) relay contacts and closed when activated. Maximum relay current: 10 A. Digital input DI1 is opto-isolated from power supply
ground. A signal ground connection must be provided to the GND connection on the Digital Input terminal block. Analogue input AI1 & AI2 is 4-20mA
non-isolated resistive load inputs. The 4-20mA source connected to these inputs need to supply the loop power.
LED status
STATUS LED (GREEN):
Continuous Flashing
Power ok and communication on S-link is present. Power is good but no S-link communication.
When installing an S-Link™ system DO NOT connect any other control equipment directly to the S-Link™ bus except original Sleipner S-Link™ products.
In case of connecting third-party equipment, it must always be connected through a Sleipner-supplied interface product.
Any attempt to directly control or connect into the S-Link™ control system without a designated and approved interface will render all warranties and
responsibilities of all of the connected Sleipner products.
If you are interfacing the S-Link™ bus by agreement with Sleipner through a designated Sleipner supplied interface, you are still required to install at
least one original Sleipner control panel to enable efficient troubleshooting if necessary.
