Secondary Power Supply Voltage Confirmation
The DVS-2000C has a power supply of +5 V, +3 V, and -5 V.
The POWER indicator and the fan uses +5 V.
Atter installation of all required boards is completed, confirm
the power supply voltage inside the unit as described below.
Test connectors in which the probe of a digital voltmeter can be
inserted for the voltage measurement of +5 V, +3 V, and—6 V are
provided on the CPU-156 board.
(1) Open the front panel and confirm that the power unit is
properly inserted and securely fixed with four screws.
(2) Tum on the power and confirm that each indicator (D4,
D5, D6) on the CPU-156 board lights.
