Binary Inputs; Analog Inputs - HindlePower ATevo Series Operating/Service Instructions Manual

12 Auxiliary Inputs/Outputs
Each relay is configurable to:
• change states based on any alarm condition or status point
• be latching or non-latching
• switch to active state after a pre-programmed delay

12.1.2 Binary Inputs

The four (4) Binary Inputs are optically isolated from ATevo and each
other. They can be configured via jumper selection to accept input
voltages of 12Vdc, 24Vdc, 48Vdc, or 130Vdc. Each Binary Input has
an associated yellow LED and a jumper selection block. The LED
serves as a debugging aid as it will illuminate when the associated
Binary Input is high (in the 'ON' state).
The Binary Inputs may be configured to be active high or active low
and generate alarms and controls such as charger shutdown. The
configuration also permits each input to be assigned a custom name
(such as '2% Hydrogen', or 'Vent Fan Fail'). ATevo will report all
activity of the input (status, alarms or log files) by the generic default
name or the custom configured name.

12.1.3 Analog Inputs

The four (4) Analog Inputs are rated for 0-10 Vdc. They utilize a
common ground, referenced to DC OUTPUT NEG, and can be used
to import generic analog values. ATevo assigns each Analog Input
a unique generic name such as 'AUX 1 input AN1'. This name can
be changed to be readily identifable by the end user (e.g. 'Ambient
Temp'). ATevo will report all status and alarms with the default name
or the custom name assigned.
The Analog Inputs include scaling configuration such that ATevo can
report their values in primary units. For example, a temperature
transducer with a 0 to 10 Vdc output can be configured to scale the
voltage value directly to the associated temperature represented by
the dc voltage. The associated 'units' name can also be configured
such that when the Analog Input value is displayed, it will display as
'80.3 F' instead of '6.2 Vdc'.
Each Analog Input can be configured to generate alarms based on
its value. Available trigger conditions to generate an alarm include
below a threshold, above a threshold, within a range, or outside a
range. Threshold and range values are configurable, and are entered
in the primary units (such as °F) based on scaling configuration.
