APDA-371 Back Panel Relay Connections
1.
TELEM FAULT N.V.
Telemetry Fault Non-Voltage. This input can be used to signal the APDA-371 that the
external telemetry system (datalogger) is not operational. This is a contact-closure input
which must be activated for a minimum of 2-seconds. If activated, the APDA will
continue to function and will log a “U” error (see section 6.5) and activate the DATA
ERROR relay output. This input can be set to normally-open or normally-closed in the
SETUP > INTERFACE menu.
2.
EXT RESET N.V.
External Reset Non-Voltage. This input is can be used to synchronize the APDA-371
clock to the external datalogger, and is often used in EARLY cycle mode (see section
8.2). This is a contact-closure input which must be activated for a minimum of 2-
seconds. The input can be set to normally-open or normally-closed in the SETUP >
INTERFACE menu.
3.
EXT RESET V
External Reset Voltage. This input is the same as above except the input is activated by
a voltage logic level instead of a contact-closure. Max 15mA @ 15V or 5mA @ 5V DC.
Five volt logic is typically used for this input.
