Programmable Current/Voltage Safety Trip Alarm
STA

SEC
TION 4
Configuring the Alarm(s)
The STA has one relay which is a Fault alarm and two user-configurable Trip alarms. The
Fault alarm has limited configuration with respect to input faults only. All diagnostic faults will
be latched and must be reset by cycling power to the unit. Input faults can be configured to be
latched/unlatched and can also be configured to be reset by the Manual Reset (MR) in addition to
front panel reset.
For more information about trip points, latching, etc., please reference the Alarm Terminology
section of this manual.

SELECT
. Use the
UP
or

SELECT
and enter your alarm trip value. Use the

Latching Alarm–
When a STA is configured with latching alarms, an alarm condition will
not “clear” (the relay will not change state) until the input returns to a non-alarm level
AND
manual reset terminals are shorted.
The manual reset terminals, labeled “MR” are located on the top row of terminals on the
STA (see Figure 3.3.).
6. At the “ENTER DELAY” display, press
SELECT.
Using the
UP
or
DOWN
buttons enter the
desired value (range is 0-120 seconds); press
SELECT
.
Delay–
When your unit is in an alarm condition, the delay is the amount of time you set
(0-120secs; 0-60secs for firmware versions 1.1.2 and earlier) to elapse before a relay
trips.
Note:
Firmware versions 1.1.2 and earlier permit 0-60 seconds time delay only. If a delay value
is entered greater than 60, the delay will not operate correctly. (The firmware revision of the unit
is displayed at power up and in the STA Device Info window of the PC Configuration Software)
