VR-5000 OPERATOR’S GUIDE
1. Recording
To start recording, press the AC breaker on the Power Distribution Unit (PDU) in the Data
Collecting Unit (DCU). Press the Battery breaker as well. When the DC power supply is
connected to the VDR as an emergency source of power, press the DC breaker. The VDR
records data automatically in both memory of the Data Recording Unit (DRU) and the
removable hard disk (HD).
Breakers on PDU in DCU
The LEDs on the PDU operate as follows.

DC Green Presence of DC power supply if connected
BATTERY Green Presence of DC power from reserve battery
(Blinking during charging)
DCU OK Green Normal operation of DCU processor (NG: Red)
SYS 1 to 3 Orange No error (Other colors: see error code list in the
operator’s manual)
2. Stopping recording
Note that the recording is stopped in the following cases;
- During essential maintenance purposes whilst the vessel is in port.
- When the vessel is laid-up.
To stop recording, depress the BATTERY, DC and AC breaker switches in this order. DO NOT
turn off the system by the main breaker on the ship's switch panel while the AC breaker is
on. If this is done, the system operates from the reserve battery.
