Installation information
The first power up of the system after installation (i.e. installing main fuse, connecting battery and
connecting the main connector to the back of the ERRS front panel) shall only be done by trained
personal familiar with the technical function and use of the ERRS system.
Note! After the battery has been connected to the system it will automatically take over the power
supply to the ERRS CP2 system if the ships emergency power supply is switched off or interrupted.
The battery will lose capacity by repeated deep discharging cycles. It is important that the battery
is disconnected in situations where an interrupted emergency power supply can be expected, as
for an example during a stay at a shipyard. Note that there is a backup battery in each ERRS CP2
Control Panel if more than one panel is connected in a network.

The HAMMAR ERRS CP2 Electronic Remote Release System is a marine-approved control system designed for the remote activation of release units, primarily for liferafts. It ensures the safe and reliable deployment of emergency equipment on vessels. The system is built to withstand harsh marine environments and provides robust protection against mechanical damage and unintended activation.

Function Description:

The ERRS CP2 system allows for the remote release of H20-ERU (Emergency Release Unit) devices, which are typically connected to liferafts or other emergency equipment. The core of the system is the ERRS CP2 Control Panel, which serves as the primary interface for system operation, monitoring, and maintenance. When activated, the control panel sends a signal to the connected H20-ERU units, initiating their release mechanism.

The system is designed with redundancy and safety features. It can operate with multiple control panels in a network, ensuring continued functionality even if one panel is compromised. Each control panel has a unique address within the network, configured during system delivery. The system also incorporates an external alarm function, which can be connected to the ship's general alarm system, providing an alert in case of system issues.

Emergency power is a critical aspect of the ERRS CP2 system. It is designed to automatically switch to a backup battery if the ship's emergency power supply is interrupted. Each ERRS CP2 Control Panel also contains its own backup battery if multiple panels are networked. This ensures that the system remains operational during power outages.

Important Technical Specifications:

• Power Supply: The system requires an emergency power supply within the range of 16 - 36 V DC.
• Current Consumption: The maximum current consumption for the system is 0.5 A.
• Internal Fuses: Internal fuses are S1 - 1.0AF 5x20 mm glass tube fuses.
• Cable Types: Marine-approved screened cables are mandatory for all connections to ensure proper system function and EMC compliance.
• Terminal Wire Area: The maximum wire area for terminals inside the ERRS CP2 enclosure is 2.5 mm².
• External Alarm Contact: The external alarm function provides an isolated, normally closed contact (when the system is OK). When an alarm occurs, the contact opens. Maximum rating: 1.0 A and 24VDC.
• Communication: Interconnection between Master and Slave control panels in a network uses RS 485 communication via 3 wires.
• Grounding: Each control panel must be connected to the ship's ground using the GROUND CONNECTION DEVICE (Part no: HM-0730 or HM-0735 for larger cables) to ensure a permanent electrical connection and proper EMC.

Usage Features:

• Control Panel Interface: The ERRS CP2 Control Panel features an intuitive interface with "MAINTENANCE," "SELECT," "ON/OFF," and "RELEASE" pushbuttons, along with scroll buttons (yellow arrow up/down) for menu navigation.
• Release Mechanism: To release, the "ON/OFF" pushbutton is held for 5 seconds, followed by holding the "RELEASE" pushbutton for 5 seconds. A progress bar on the display indicates the activation process.
• Remote Pushbutton/Release Switch: The system supports remote pushbutton/release switches, which must be installed in a protected enclosure to prevent unintended activation and mechanical damage. These switches are lockable and feature a seal that breaks upon opening, indicating prior use.
• System Status Monitoring: The control panel display provides messages regarding system status, including error reports (e.g., "there are no errors" or "error on: OUTPUT 1").
• Maintenance Menu: A dedicated "MAINTENANCE" menu allows access to system diagnostics, including "SYSTEM ERRORS" and "RESET SYSTEM" functions.

Maintenance Features:

• Installation Verification: A detailed installation and test procedure is outlined to verify correct connections and functionality. This includes:
  • Securing liferafts to prevent unintended launching.
  • Disconnecting H20-ERU wires and connecting jumper wires in ERU connector boxes.
  • Checking for "no errors" in the "SYSTEM ERRORS" menu.
  • Systematically removing jumper wires to test individual output error reporting.
  • Reinstalling jumper wires after testing.
• Activation Test: The system recommends using an ERU Emulator (HM-0467) for activation testing. Alternatively, 200mAF glass tube fuses can be used, which will flash briefly upon activation if the output is working correctly. The test involves:
  • Connecting an ERU emulator to each output sequentially.
  • Activating the release function from the control panel.
  • Verifying the emulator flashes red (indicating activation) or green (indicating no activation).
  • Resetting the system after all outputs have been tested.
• System Reset: The "RESET SYSTEM" function in the maintenance menu restarts and resets the control system.
• Battery Management: It is crucial to disconnect the main backup battery during extended periods of interrupted emergency power (e.g., at a shipyard) to prevent deep discharging cycles and preserve battery capacity.
• EMC Cable Gland Maintenance: The metal EMC cable glands are designed for good connection between the cable gland and the cable screen. Proper installation involves stripping the cable, folding back the screen, and inserting it until the screen aligns with the inner end of the gland, ensuring contact with the EMC fingers when tightened.
• Ground Connection Device: The GROUND CONNECTION DEVICE ensures a good permanent electrical connection of the control panel enclosure to the ship's ground. It must be mounted close to the ERRS CP2 control panel.
• Documentation: A "CHECKLIST FROM INSTALLATION AND TESTING OF HAMMAR ERRS CP2 SYSTEM" must be filled in and returned to CM HAMMAR AB to activate the product guarantee.
