AtlasPC Digital Control, Vol. I

Woodward

Input Power

The AtlasPC control requires a nominal voltage source of 18 to 32 Vdc. Input
power requirements vary depending on the control version. Table 2-1 contains
information for the maximum configuration.

Power must be applied to the AtlasPC control at least 60 seconds
prior to expected use. The control must have time to do its power up
diagnostics to become operational. Failure of the diagnostics will
disable control function.

The AtlasPC power supply board must have the input power
removed before installing or removing.

This equipment is suitable for use in Class 1, Division 2, Groups A,
B, C, and D, or non-hazardous locations only.

Wiring must be in accordance with Class I, Division 2 wiring methods
and in accordance with the authority having jurisdiction.

Do not connect more than one main power supply to any one fuse or
circuit breaker.

Power supply output must be of a low impedance type for proper operation of the
control. DO NOT power a control from a high voltage source containing dropping
resistors and zener diodes. If batteries are used for operating power, an
alternator or other battery charging device is necessary to maintain a stable
supply voltage.

Significant inrush currents are possible when current is applied to the AtlasPC
control. The magnitude of the inrush current depends on the power source
impedance, so Woodward cannot specify the maximum inrush current. Time-
delay fuses or circuit breakers must be used to avoid nuisance trips.

Input Power Wiring

Protective earth ground (PE) must be connected to the chassis at the termination

point on the back side labeled with

. The power supply grounding

terminals should also be connected to earth to ensure grounding of the power
supply printed circuit boards. The grounding conductor must be the same size as
the main supply conductors or the PT wires, whichever is larger.

Note that the control’s power supplies are not equipped with input power
switches. For this reason, some means of disconnecting input power to each
main power supply must be provided for installation and servicing.
