Model Numbers and Options
The following section provides details of the Moore Industries model number and the available
options for the STA.
Moore Industries model numbers for STA are structured as follows:
STA / HLPRG / 3PRG / U / -AO [DIN]
Unit / Input / Output / Power / -Options [Housing]
Refer to
Section 10 Ordering Information
for a quick reference table of ordering information
INPUT
HLPRG
The STA (HLPRG) supports either current inputs from 0-50mA (4mA minimum span) or
voltage inputs from 0-11V (1V minimum span). These inputs can be trimmed and scaled,
refer to the Configuring Inputs section of this manual for additional information.
OUTPUT
3PRG
The STA has three programmable contact closure alarms. One relay is factory configured
as a Fault alarm and the remaining two relays are user-configurable Trip alarms. A dual
color LED (Red/Green) is provided with each alarm to indicate its condition.
The fault alarm trips on a self-diagnosed failure within the STA or on any of its inputs.
This alarm is latching and has to be reset by the user. Only user configuration faults will
clear automatically once the configuration is valid. Input faults can be configured to Latch
or not Latch and can be cleared by the “RESET FAULT” menu or by the MR terminals if
configured to reset both latched Tripped Alarms or input faults. Self-Diagnosed unit faults
can only be cleared by power cycling the unit.
Note:
For STA units with firmware versions 1.5 and earlier, the fault alarm has no configuration
options, is always latched and cannot be reset by Manual Reset (MR).
For more information refer to the Diagnostics and Fault Alarm section.
The Trip alarms are configurable for high or low trip with an adjustable dead band. These
alarms can be latching or non-latching. Latched alarms are reset through the Manual
Reset (MR) terminals.
The relay outputs have a 3A@250Vac or 3A@30Vdc, 50/60Hz non-inductive contact
rating. The contact arrangement is SPDT (1FormC). All outputs are fail safe and will
deenergize to trip (DET) with normally open (NO) and normally closed (NC) relay contacts.
Refer to the Alarm Terminology and Configuring the Alarms sections of this manual for
additional information.
