Programmable Current/Voltage Safety Trip Alarm

STA

Section 1 - Introduction

This is the user’s manual for Moore Industries’ STA (HLPRG): Programmable Current/Voltage
Safety Trip Alarm.

The Moore Industries’ Safety Trip Alarm (STA) is designed and manufactured to provide a high

level of availability for safety critical applications and for use as a component part of a safety
instrumented system.

Overview

This manual contains all of the information needed to configure, install, operate and maintain this
product. When the STA is used in a SIL rated safety application (as defined by IEC 61508), the

Safety Instrumented Systems section of this manual must be read and followed in order for the

STA to meet its IEC 61508 certification requirements.

Description

Moore Industries’ STA (HLPRG) is a Programmable Current/Voltage Safety Trip Alarm.

HLPRG

SECTION 1

The STA monitors a process variable and provides two fully user-configurable contact closure
outputs that can be individually programmed to trip whenever the input falls outside a user-set,

high or low trip point. It also has one fault alarm output which is triggered by a self-diagnosed

failure of the input or the STA itself. The STA is typically used to activate a warning light, bell
or buzzer; or to initiate a system shutdown. Thus, the instrument acts as a simple, but highly

reliable and effective means of monitoring and safe-guarding a process.

The STA may be configured using front panel push buttons and/or Moore Industries’ PC
Configuration Software. A large 5-digit display shows menu prompts during push button

configuration and process variable and status messages during normal operation.

The STA also has a password security feature to limit access to the front panel configuration.
Refer to Security Settings in the Installation and Wiring Section for more details.

All STA diagnostic faults are latching and input faults can be configured to latch or not latch.
User configuration faults will clear automatically once the configuration is valid. If input faults are
latched, these can be cleared by the “RESET FAULT” menu and the Manual Reset (MR) terminal
can also be configured to reset both latched Trip Alarms and input faults. Unit faults such as
internal diagnostics will always latch the Fault Alarm and the unit must be power cycled to clear

the alarm.

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).

Alarm Terminology

Before setting up the STA, or incorporating the unit in your application, Moore Industries

suggests that all users take a few moments to become familiar with some of the terms
associated with the use of process instrumentation alarms.

Figure 1.1. How Alarms Work with the Process Input

SECTION 1

User’s Manual

225-748-01L

February 2017

The Trip Point is the process input level at which the user wants an alarm relay to change state,
typically going into an alarm condition, or “tripping”. In the STA, the user sets the trip point for

each alarm relay.

High/Low Alarms; High Alarms trip when the process input goes above the trip point. Low
Alarms trip when the process input drops below the trip point. Each of the STA relay outputs can

be set by the user to function independently as either high or low alarms.

Latching and Non-latching Alarms; once tripped, a latching alarm remains in an alarm state
until the input returns to a non-alarm level AND is manually reset. Non-latching alarms return to
a non-alarm state whenever the process input returns to the Reset Point. The STA relays can be

www.miinet.com Moore Industries-International, Inc.

set by the user to function as either latching or non-latching.

The Reset Point is the process input level at which the user wants an alarm relay to change

state, typically going from alarm to non-alarm. The reset point is not necessarily the same as the
trip point, because most applications call for a bu󰀨er zone or deadband around the trip point to
allow for minute uctuations in the process input. In the STA, the reset point is determined by the
deadband setting. Latching STA alarms will not “clear” unless the reset point has been reached

or passed AND the manual reset contacts have been shorted.

The deadband is the range in which an alarm remains tripped even after the process input has
returned to or passed the trip point. Deadband is not required. When it is not incorporated into a

non-alarm application, the trip point and reset point are the same. The deadband of the STA is

set by the user.

- 10 -

User’s Manual
225-748-01L
February 2017

Failsafe Alarms are de-energized when tripped, energized when the process input is at a
non-alarm level. Non-failsafe alarms are energized whenever tripped, de-energized when the
process input is at a non-alarm level. The relays in the STA are failsafe only. Normal is the term
used to describe the “shelf-state” of relay contacts. The contacts of a Normally Open relay are
open (innite resistance) when the relay is not energized. The contacts of a Normally Closed

relay are open when the relay is energized (closed when not energized).

Note: Sometimes a non-alarm input level is referred to as being in a “normal” condition. This
practice is intentionally avoided in this manual. Do not confuse the term “normal”, as in Normally
Open or Normally Closed, with a non-alarm input condition. In this manual, “normal” is an
exclusive reference to the shelf state or quiescent state of an alarm’s relay contacts, whether

open or closed.

Section 2 - Calibration and Bench Check

It is recommended that you perform a bench check on your instruments prior to installing them in
your application.

Calibration

A true calibration of the STA can only be performed at Moore Industries using specialized

equipment. We recommend that you check the calibration every year and re-calibrate only when

necessary.

However, input trimming increases the measurement accuracy of your instrument by matching
the reading of its actual input to its scaling. The STA o󰀨ers the use of a factory-congured
trimming feature (‘FCTRY TRIM”) or user-set, one-point or two-point (“USER 1 PNT” or “USER 2
PNT”) trimming.

Please refer to Section 4 of this manual for instructions to perform Input Trimming via Push
button panel or Section 5 using the PC Conguration Software.

User’s Manual

225-748-01L

February 2017

Likewise, output trimming increases the measurement accuracy of the STA by calibrating its
Analog Output to the device that is receiving the output. This ensures that the instrument is being

correctly interpreted.

Please refer to Section 4 of this manual for instructions to perform Output Trimming via Push
button panel or Section 5 using the PC Conguration Software.

Bench Check

We highly recommend that you perform a bench check of your STA prior to installing it in the
eld. This will ensure that the STA is operating within your expectations or requirements.

The bench check is a quick way to determine that your STA is functioning as expected.
Depending on your organization’s requirements, you may also be required to perform a complete
Proof Test on your STA. The instructions for the Proof Test can be found in Section 7 of this

manual.

As a prelude to performing the bench check you should congure your STA as it is to be used
in your nal application. Refer to Section 4 for the STA Front Panel Conguration instructions.
These instructions are used if you are conguring your STA by using the front panel push
buttons. Section 5 contains the instructions for conguring your STA using the STA PC
Conguration software.

The equipment necessary to perform a bench check can be found in Table 2.1.

Bench Check Procedure

1. Current or Voltage Input:
In order to provide an input to your STA HLPRG you will need to use an appropriate input
source. By example – if you plan to use your STA with a current (mA) input you will need

to use a milliamp source to provide the appropriate input during your bench check. The

same goes for a voltage source. Use whichever input source is correct for your intended
application. Please see Figure 2.1 for the correct input connections.

2. Power Input:
Connect the appropriate power source as shown in Figure 2.1.

3. Set your input source to the low end of your congured input span. By example – if your
input is congured for a current (mA) and your input range is set for 4-20mA then use a
current source and set it to 4mA. Verify that the STA is reading 4mA on its display window.

4. Set your input source to the high end of your congured input span and verify that the STA’s
display window correctly reects the input.

User’s Manual

225-748-01L

February 2017

SECTION 2

5. Set your input source to a value higher or lower than your congured input span and verify
that the Fault Relay changes state. The Fault Relay can be reset via the front panel push
buttons or via MR terminals (if congured).

6. Temporarily remove one of your input connections to verify that the Broken Wire feature
is working. Note: the Fault Relay can be reset via the front panel push buttons or via MR
terminals (if congured).

7. Alarm Relays:
By adjusting your input up and down you can conrm the operation of the Alarm Relays.
Use your multimeter (set to ohms) to verify the state of the relay contacts.

Units with the Analog Output option (-AO)

The STA’s analog output can be user congured one of three ways – 1) 0-20mA sourced with
voltage sourced by the STA (also referred to as Io Source) or 2) 0-20mA with voltage sourced by
the DCS (also referred to as Io Sink) or 3) 0-10V (also referred to as Vo).

Note that even though 0-20mA is the range of the analog output it can be scaled by the user for a
narrower range (such as 4-20mA). The same goes for the voltage output.

1. Connect the analog output as per Figure 3.3. Use the terminals that are correct for your
application.

2. When testing the milliamp output it is best to use a 250 ohm precision resistor across the
output terminals (as shown in Figure 3.3). Then you can use your multimeter (set to voltage)
to read the voltage drop across the resistor. Hence a reading of 1V means that the analog
output is putting out 4mA, and a reading of 5V equates to a 20mA output. If using the STAs
voltage output terminals (+/-Vo) the voltage can be read directly with your multimeter.

3. Set your input simulator to the low end of your congured input span. Verify that the analog
output is correct. By example – a 1V reading across your 250 ohm resistor equates to a
4mA output.

4. Set your input simulator to the high end of your congured input span. Verify that the analog
output is correct. By example – a 5V reading across your 250 ohm resistor equates to a
20mA output.

You have now conrmed that your STA is operating correctly and can now be condently

installed into your application.

Equipment Ratings

Contact Relays

The STA does not generate hazardous voltages but can switch outputs up to 3A at up

to 250Vac or 30Vdc on its relay contacts. Products connected to the STA should be

designed to receive this type of input.

Analog Output

The STA does not generate hazardous voltages, it provides a low current (4-20mA) or

voltage (1-5V) input and a 4-20mA output. Products connected to the STA should be

designed to receive this type of input.

Warning: If this unit is used in a manner not specified by Moore Industries, the protection
provided by the equipment may be impaired.

Switches and Circuit Breakers

For STA AC powered units, a switch or circuit breaker must be wired in series with the AC power

conductors. The switch or circuit breaker used must be located within three meters of the unit.
The circuit breaker or switch will only remove power to the unit; hazardous voltages may still be
connected to other terminals on the unit.

Programmable Current/Voltage Safety Trip Alarm

HLPRG

STA

SECTION 3

Power Supply Wiring

All power connections should be made with 14 or 16 AWG (2mm2 or 1.3mm2) wire.

The end of each conductor should be stripped no more than 0.25in (7mm). The end of the
stripped wire should be tinned with solder, or inserted into a ferrule and crimped before being

placed into a terminal block.

Tighten the screws on the terminal block to 4.4 - 5.3 lbf/in2 (0.5 - 0.6 N/m2).

Protective Earth Conductor

The Protective Earth Conductor shall be of equal or larger size wire than the other two power
conductors. The Protective Earth Conductor shall be the first conductor connected to the unit

when the unit is being wired. It shall be the last conductor removed when the unit is being
un-wired.

Input/Output Wiring

The Input/Output connections can be made with 14 to 24 AWG (2.5mm2 to 0.2mm2) wire. The
end of each conductor should be stripped no more than 0.25in (7mm). Tighten the screws on the

terminal block to 4.4 - 5.3 lbf/in2 (0.5 - 0.6 N/m2).

Recommended Ground Wiring Practices

Moore Industries recommends the following ground wiring practices:

• Any Moore Industries product in a metal case or housing should be grounded.

• The protective earth conductor must be connected to a system safety earth ground before
making other connections.

• All input signals to, and output signals from, Moore Industries’ products should be wired

using a shielded, twisted pair wiring technique. Shields should be connected to an earth or

SECTION 3

safety ground.

• For the best shielding, the shield should be run all the way from the signal source to the
receiving device. (see Note below)

• The maximum length of un-shielded input and output signal wiring should be 2 inches.

Note: Some of Moore Industries’ instruments can be classified as receivers (IPT2, IPX2, etc.)
and some can be classified as transmitters (TRX, TRY, etc.) while some are both a receiver and
a transmitter (SPA2, HIM, etc.). Hence, your shield ground connections should be appropriate for
the type of signal line being shielded. The shield should be grounded at the receiver and not at
the signal source.

User’s Manual

225-748-01L

February 2017

CE Certification-related Guidelines

Installation of any Moore Industries’ products that carry the CE marking must adhere to the
guidelines in the Recommended Ground Wiring Practices section in order to meet the EN 61326
requirements set forth in the applicable EMC directive.

The Low Voltage Directive also applies to the AC powered versions of the STA and/or when

connecting any of its output relay contacts to voltages greater than 50 vac. In order to comply

with EN61010-1 (Low Voltage Directive) all guidelines in this section must be followed.

Contact/Load Suppression

When the instrument relays are used to switch an inductive load such as an external relay coil,
contactor, solenoid, large voltage spikes may be created in nearby cable harnesses. When
excessive, these voltage spikes can disrupt the operation of all nearby electronics including this
product. Inductive loads should have suppression devices installed at the load (for external
relays this would be right across the relay coil itself). Usually this is a simple diode for dc
circuits. AC circuits routinely use an R-C snubber. Please follow the external load manufacturer

instructions for their recommended suppression kits.

Scaling the Input

Figure 4.4 gives an overview of the Input Scaling menu.

Scaling allows you to take your PV (Process Variable) reading and transform it to a custom
engineering units range. PV is the unit read after selecting your input type. For example,
choosing a volts input would then produce a PV displayed in volts.

Also known as “Smart Ranging”, scaling of the STA allows you to set the zero and full scale
values of the input from the intended application, without having to connect the unit to any

Programmable Current/Voltage Safety Trip Alarm

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 4

section of this manual.

1. At the “CONFG ALARM” menu, press SELECT. Use the UP or DOWN buttons to toggle
between both trip alarms. When the desired alarm appears, press SELECT.

2. At “ENTER TRIP”, press SELECT and enter your alarm trip value. Use the UP or DOWN
buttons to set, adjust your trip value; press SELECT.

If you prefer to capture the input trip value instead of entering it, you must use the “INPUT

TRIP” menu. To do so, bypass the “ENTER TRIP” menu by using the DOWN button to

scroll to the menu; press SELECT. Ensure that the value you wish to capture is present
then press SELECT.

3. Press SELECT at “ENTER DB” and enter your dead band value using the UP or DOWN
buttons. Press SELECT once your desired setting appears.

4. Pressing SELECT at the “SET HI/LO” menu directs you to configure the alarm type as an
“ALARM HI” or “ALARM LO”. Use the UP or DOWN buttons to reach your selection and

press SELECT.

ALARM LO– You are notified if your process input drops below your trip point setting.

ALARM HI– You are notified if your process input exceeds your trip point setting.

5. At the “SET LATCH” display, press SELECT and choose “LATCH ON” or “LATCH OFF”

using the UP or DOWN buttons; press SELECT.

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.

User’s Manual

225-748-01L

February 2017

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).

7. If you are to program Alarm 2, use the UP or DOWN buttons to reach “CONFG ALRM2”
and repeat the steps performed from Alarm 1 using the appropriate values and settings.

8. At the “INPUT FAULT” display, press SELECT, this will display “LATCH YES?” to set latch

press SELECT or press DOWN button to display “LATCH NO?”, press SELECT here if
you want to disable latching.

Damping– Output damping applies filtering to slow the response of the output so that

momentary input variations reduce output spikes. The time setting (0-30 seconds) defines

how long it takes for the output to reach 63% of the target value.

3. To set damping, press SELECT at the “SET DAMP” display. Use the UP or DOWN

buttons to enter a value between 0 and 30 seconds; press SELECT.

4. Press SELECT at “FAIL MODE” to configure the analog output response to an input

failure. Input failures are a subset of diagnostics limited to:

1) ADC Diagnostics

2) Broken Wire

3) Input Saturation

4) Configuration / Calibration Validation.

Choose from “FAIL HIGH”, “FAIL LOW” or “HOLD LAST,” then press SELECT. This sends
you to “EXIT AOUT”.

FAIL HIGH/FAIL LOW– either of these options will send the analog output to a High or

Low (see Specifications table), respectively.

HOLD LAST– This will cause the analog output to maintain the last valid value present

before the failure.

Section 5 - STA PC Conguration

Note: Earlier versions of STA were shipped with Transfer Utility Software not PC Configuration
Software. This allows you to upload/download, view and print but not change your instrument’s
configuration. For the latest version of PC Configuration Software, please go to www.miinet.com

Installing the Configuration Software

Refer to Table 5.1 for the equipment needed.

1. Check the Moore Industries website @ www.miinet.com for the latest software package
to ensure you have the latest release. Also if you are not able to go online install software

using the included Moore Industries Interface Solution PC Configuration Software

CD. Insert CD into the CD drive of the PC. Access the CD and open the “STA PC
Configuration Software” folder.

2. Double-click the installation program located in the folder. Follow the prompts to correctly

install the program.

Once the Configuration Program is installed onto your PC, the STA can be connected to

equipment to simulate input and monitor output. You can then change the operating parameters
of the alarm.

No Unit Needed

It is not necessary to connect the STA to a PC to create configuration files using the software.
The Configuration Program can be run without connecting an STA, and most parameters can be
set without the benefit of an input from a sensor or STA.

HLPRG

SECTION 5

This makes it easy to create a set of operating parameters, save them to disk, and download

them to one or more instruments at a later time.

The STA must be connected to the PC in order to: trim input, trim output, assign a tag, perform a
loop test, receive (via download) a configuration file, and save the configuration file (via upload)
from the STA’s memory.

Selecting Model Type

User must select model type and Firmware version when the software is opened without a
unit connected as shown below. Unit type is determined by Input Type and Analog Output
Configuration and firmware Rev, additional features added if firmware is v1.6 or greater. When a

unit is connected the software will select the correct type automatically.

Connecting the STA to the PC

Connect the RS-232 or USB end of the cable to the PC’s COM/USB port. .

See Table 5.1 for information on the necessary equipment.

www.miinet.comMoore Industries-International, Inc.

HLPRG

STA

Programmable Current/Voltage Safety Trip Alarm

PC Software Configuration

One of the benefits of the STA is that you may either use the external push button controls to set
up the instrument, or with Moore Industries’ Intelligent PC Configuration software on your PC.

When using the software program, settings are downloaded to the instrument in the form of
a Configuration File and stored in the instrument’s memory. You can save a backup copy of
the file on your PC hard drive or disk. The STA communicates with the PC through an RS-232
connection or USB Communications Cable.

SECTION 5

Note: Refer to the STA HLPRG Quick-Start Guide to see the default factory settings for your unit.

Caution: Unplugging the programming cable or resetting power while downloading to the unit

could result in a default configuration / calibration and the unit may have to be returned to the
factory.

of mains-induced noise. The input filter frequency value should be set to the frequency of the

local AC supply– either 50Hz or 60Hz.

Input Range– Allows you to set your Input Zero and Full range values within the range chosen in

the Input Type section.

The desired Input Zero and Full range values can be entered via your PC keyboard.

Warning: The default value for INPUT OOR is 3.84mA-20.16mA for Current Input Type (1%).
For safety applications, the INPUT OOR value must be set to 3.68mA-20.32mA (2%) or less.

Note: Entered Values must be within the displayed Input Limits. Minimum Span is also
displayed and Span between entered values must conform to this minimum value. Refer to

Table 9.4 for Input Limits and Minimum Span for each specic Input Type.

Note: The actual value must be entered in the Out Of Range elds, percentage is automatically
displayed below this eld. Values entered in the Out Of Range elds for the Input Full and Input

Zero are limited 0% to 5 % of the Span. Span is displayed above along with Sensor Limits and
Minimum Span.

Note: For STA units with rmware versions 1.5 and earlier, OOR is not congurable and the

SECTION 5

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) feature in addition to

front panel reset.

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 MR.

For more information about trip points, damping, etc., please reference the Alarm Terminology in

Section 1 of this manual.

Trip Point – Set this Point to have STA unit notify you if your process input drops below, or
exceeds your trip point setting depending on Alarm Mode select by user.

Dead Band– The Dead Band is the range within which an alarm relay remains in an alarm
condition even after the monitored process variable input has returned to a safe level, at or below/

above the trip point setting.

Delay - When your unit is in an alarm condition, the delay is the amount of time you set to elapse

before a relay trips. This can be set in increments of 1 second from 0-120 seconds.

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).

unattended for extended periods of time.

STA Diagnostics & Fault Alarms

The STA has a high level of diagnostic capability to continually monitor itself and its input. This
section outlines these diagnostics and functionality of the alarms. For a full list of diagnostic

messages and corrective actions please refer to Table 6.1.

User’s Manual

225-748-01L

February 2017

Internal diagnostics

On power up the unit runs through a thorough diagnostic test (RAM and ROM TEST messages
are displayed), an initialization process (SYS INIT is displayed) and waits the congured amount

set in the Startup Delay Menu before the fault alarm is cleared. If any failure is found during

power up, the fault alarm will not be cleared and an error message will be displayed. Once in
operation, the unit continues diagnostic tests in the background and will set the fault alarm on

any failure.

Note: For STA units with firmware versions 1.5 and earlier, the startup delay cannot be
configured and is set to 0.

All internal diagnostic faults will cause the fault relay to de-energize and remain in a latched
state. Spurious faults that can be caused by external factors such as transients or surges, may

result in a diagnostic failure and trigger the fault alarm. While some faults may be cleared via the

menu system or MR Terminals (if congured), it is recommended that the STA be power cycled
to clear the latched fault alarm. If the error persists, then please record the error message and
contact MII Customer Support for further assistance.

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 MR.

Note: The trip alarms and analog output (AO) are independent from the fault alarms and will be

unaected by the fault alarms (however they may be aected by the specic failure in the unit).

Configuration diagnostics

On power up the stored conguration is validated. If it is invalid then the fault alarm will be set.
To clear the alarm, use the menu system, to reset to the factory conguration (FCTRY CONFG
selection in the options menu), then congure as appropriate for the application.

Before saving a new conguration to the unit, it will be checked for validity. If it is invalid, the
fault alarm will be set. Once the conguration is corrected, the fault alarm will be cleared.

Input diagnostics

The STA has extensive hardware diagnostics of the input to detect broken wire and saturation. It

also detects out of range and linearization errors.

Broken wire is automatically set on the STA and enables the system to distinguish between a

low trip condition (which sets the trip alarm) and a failed transmitter or open input (which sets the
fault alarm).

All input faults will be alarmed on the fault relay. Depending on the conguration, they may
or may not be latched (default is latched). A latched input fault alarm can be cleared by rst
clearing the input failure and then using the conguration menus or MR (if congured) to reset
faults. If the input error is not cleared when resetting the fault alarm, the error condition will

immediately be re-applied and will not cause the relay to glitch.

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 MR.

Note: The trip alarms are independent from the fault alarm and will be una󰀨ected by the fault
alarm. Therefore if the trip alarm has already been activated it will remain so but will NOT be
activated by a broken wire or input saturation error. The analog output (AO) will respond to an
input error and will be set to its programmed fail response. For broken wire detection, this only
applies if the input is immediately broken. If there is degradation of sensor wires, false readings

could occur before the wire breaks and the trip alarm could be activated before the fault alarm.
(Slow degradation is characterized by events that occur over a span of a second or so).

STA Diagnostic Messages

Every STA is subjected to a complete suite of operational checks and tests prior to its shipment.
Occasionally, however, units can sustain damage in transit from the factory to the user.

The STA is also equipped with a full set of internal diagnostics that check operation and
configuration upon power-up. If there are problems with the unit, or with conflicting operating
parameter settings, the LCD will display an error message upon unit start-up, and the fault alarm

will remain set. Identical diagnostics are performed in the background during run time. If a fault

is detected, the fault alarm will immediately be set, and an error message will be displayed.

STA

Section 7 - STA in Safety Instrumented Systems

The STA is designed for use as an element of a safety instrumented system as dened by
IEC61508-4 para 3.4.1.

This user manual contains all of the information needed to congure, install, operate and
maintain this product. For safety applications the STA must only be used in accordance with this

information and the restrictions and limitations as detailed below.

Functional Safety Description

The STA has been certied, by exida ®* to IEC61508:2010 for systematic integrity up to SIL3
and for random integrity up to SIL2. This means that an STA is approved for single use in Safety
Instrumented Systems (SIS) up to SIL2 and in a redundant architecture (1oo2, 2oo3, etc.)
up to SIL 3. It is classied as a Type B device according to IEC 61508. Therefore, table 2 in
IEC61508-1 and table 3 in IEC61508-2 provide the Safety Failure Fraction (SFF) and PFDAVG
requirements for a given SIL rating.

The STA is a programmable alarm which accepts current and voltage as input for High-Level
(HLPRG) units. Two programmable relays, used as process trip alarms, and one SPDT relay,
used as the fault relay are provided as outputs. An optional Analog Output (AO) is also provided.
Operating power is supplied external to the unit. For safety systems, the STA performs as

an alarm trip and/or transmitter which processes the input signal(s) and sets the output trips

and optional 4-20mA output current according to its conguration. The safety output is either
congured as an output trip or as an analog output. In both cases the fault relay must be used to

detect faults.

HLPRG

SECTION 7

Note: For units with rmware V1.2 or earlier, the STA is certied to 61508:2000 by TUV
Rhineland. For units with rmware V1.3, the STA is certied to 61508 by both TUV Rhineland

and exida®. For units with rmware V1.5 and later, the STA is certied to 61508:2010 by exida®.

Failure Rate Data

The STA FMEDA report (Moore Industries’ Document No: 700-702-32) provides the failure
data (including PFD and SFF) required for calculations to use the STA as part of a Safety

Instrumented System.

Product life

The product life of the STA is 20 years (based on worst case component life data).

However, IEC 61508-2, section 7.4 states that a useful lifetime based on experience has more
weight than the calculated gures; Note 3 in the section comments that the useful lifetime of a
transmitter is most often within 8 to 12 years.

Installation

No special installation is required in addition to the standard installation practices in this user

manual. Refer to the specications table of this user manual for ambient conditions and required

power input.

Prior to use in a safety function, the user must validate the operation of the device o󰀪ine (see
bench check in Section 2).

HLPRG

STA

Programmable Current/Voltage Safety Trip Alarm

Configuration

The unit can be congured using the front panel buttons or PC Conguration Software as

described in this manual.

Note: While the system is in conguration mode the system is in an o󰀪ine mode and is not

performing the safety function

Do not attempt to connect the STA communications cable to the STA while the output relays are

connected to a load.

SECTION 7

After making any conguration changes, the user must validate the operation of the STA o󰀪ine
to ensure that the changes work safely, prior to putting it back into operation.

The following considerations and restrictions will apply when using the STA in a safety

application:

Trip Relay used as safety output: One or both trip alarms must be connected to the actuator/

equipment under control (EUC). The separate dedicated fault relay must either be
connected in series with the trip alarm OR connected to a separate indicator to only alarm
the fault while maintaining the process in normal operation. Refer to Figures 8.1 and 8.2

in Section 8 for typical STA configurations.

Analog Output (AO) used as safety output: The STA may optionally be provided with an

analog output (AO) which can be used for connecting to displays, control systems, etc.

User’s Manual

225-748-01L

February 2017

For STA units with V1.2 rmware or less, the AO is NOT certied for safety use and must not be
used as any part of a safety loop. The analog circuit is isolated from the STA safety circuits and
consequently its failure will not compromise the certied safety function of the STA.

For STA units with V1.3 rmware or later, the AO is certied for safety use and can be used in the
safety path. Figures 8.4 and 8.5 in Section 8 for typical congurations.

The AO must be configured as follows: The AO is a current output set at 4 to 20mA. The AO

is set to fail low (fail high is a non fail-safe condition when power is lost). The logic solver

is either configured to detect a ‘fail low’ condition for SIL1 applications (anything less than

4.0mA is detected as a fault) or a `fail windowed’ condition for SIL2 applications (anything
outside the 4-20mA range is detected as a fault). The fault alarm relay is used by the logic

solver to detect failures.

Note: When conguring Out of Range for STA units with rmware V1.5 or later, the Out of
Range value must be congured for 2% or less (default setting is 1%).

High Availability Configuration

(Figures 8.1 & 8.2)

Separating the process and fault loads increases availability but its use must be authorized only

after a careful hazard and operability study involving suitably qualied persons.

Warning: With this conguration, an internal STA fault would not trip the EUC.

Sensor Types

The STA is designed for use with a wide variety of inputs. It is the end user’s responsibility to
ensure that the chosen sensor is capable of achieving the required loop SIL.

User’s Manual
225-748-01L
February 2017

Broken Wire Detection

The STA is provided with the facility to detect both open circuit and short circuit input. This

broken wire detection must always be enabled. This is essential to ensure that dangerous failure

of the sensor or signal input is detected by the STA and consequently alarmed.

Warning: For HIGH LEVEL INPUT, the Lower Range Value (LRV) must be set higher than zero. Broken

Wire Detection will be disabled if LRV is set to zero and will invalidate the safety function.

Sensor Trimming Enable/Disable

Sensor trimming should be used with extreme care as this facility is allowed to trim the sensor
accuracy by as much as 2% of the trimming point value. It is the user’s responsibility to ensure

that the safety application can tolerate this.

Latching Mode Enable/Disable

The STA is provided with the capability to latch on a trip, i.e. once the output process alarm

relays have de-energized they will remain de-energized until either the manual reset contact is
closed or the unit is power cycled. The use of this facility will be determined by the application.

It is recommended that if the output state is latched externally to the STA, the STA latching option
is disabled. Please note that the fault alarm can be congured to Latch or not Latch on Input
Faults. The Input Fault is latched by default.

Programmable Current/Voltage Safety Trip Alarm

STA

HLPRG

SECTION 7

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 MR.

Remote Manual Reset – Procedural Issues

The STA has a facility for the connection of a remote switch to release the latch on the outputs, if
congured, this includes input faults (congurable in units with rmware V1.5 or later).

This function is meaningful only when automatic latching of outputs and/or input faults is selected

in the conguration. If the manual reset is made part of the safety procedure, it must only be

used under strict supervisory and procedural control. The use of a key operated momentary
contact is suggested.

Process Safety Time

Process safety time is the minimum time from the initiation of a hazardous event to the point
where the hazardous event is unavoidable. Any safety function designed to either prevent the
event or at least mitigate its e󰀨ect must be capable of performing its specied safety function in a

time period very much less than the process safety time.

The STA has a characteristic response time (end to end) of 256mSec. The total diagnostic test

time of the unit is 15 minutes.

Operation and Maintenance

Proof Test Procedure

It is normal practice with SIS that the components undergo periodic proof tests to expose
dangerous faults that are not detected by internal diagnostic tests. Thus, this section species
how the dangerous undetected faults determined during the FMEDA can be detected during

proof testing.

Calculation of the required proof test interval can be made using data in the FMEDA report

SECTION 7

(Moore Industries’ Document No: 700-702-32).

The proof tests described in Table 7.1 and Table 7.2 are designed to cover all possible

dangerous undetected faults that can be detected without opening the unit (proof test coverage

is 97%). Periodically testing the STA, using the proof test steps outlined below, the accumulated
PFDAVG value can be reduced to a smaller but non-zero value. To completely test for all possible
dangerous undetected faults, the unit must be sent back to the factory for a comprehensive proof

test inspection.

User’s Manual

225-748-01L

February 2017

Repair and Replacement

The STA is not intended to be repaired on site and has no components needing maintenance
or regular replacement. On device failure, the STA should be returned to Moore Industries
Worldwide Headquarters in North Hills, CA 91343 U.S.A for repair and refurbishment (refer to
Returns Procedures at the end of this manual).

The STA is a certied Safety component. Repair or replacement of any component without
authorization from Moore Industries International, Inc. will invalidate any remaining warranty and
the IEC61508 certication.

Recording and Reporting of STA Performance

It is the end user’s responsibility to maintain records of all safety component failures, especially
those that might be classied as potentially dangerous.

This feedback data not only helps the supplier identify and rectify reliability issues but also to

provide quantitative data to increase condence in the FMEDA analysis of dangerous failure
rates. Please ensure that any components returned to Moore Industries International, Inc. are
returned with a clear report identifying the fault experienced.

Step Action

1 Bypass the safety PLC or take other appropriate action to avoid a false trip

Disconnect all wires from the STA. Using an ohmmeter, measure the resistance between the case
and all exposed pins on the front. Verify that the measured resistance is greater than 1 MΩ

2

with the exception of the GND pin which should have a 0Ω resistance. This test for shorts between
the power, input and output to case and verifies that ground is connected to case.

Resupply power. Connect a loop device powered by the TX output. Configure all alarm outputs
such that:

3

i. Each alarm is set to the midpoint of the configured range

Alarm 1 is set to trip when the input is below the midpoint, Alarm 2 is set to trip when the input

ii.

is above the midpoint

Cause the loop device to go to its maximum output value. Verify that the device is not power
starved, eg displaying symptoms of power cycling, browning out, etc. Verify that the STA is
measuring the input from the loop device correctly by viewing the display or using the STA transfer

4

This verifies the proper operation of the TX supply circuit and that the supplied current is not below
the maximum requirements of the loop device

Remove loop device from previous step and install one (1) 2k ohm (1/2W) resistor to each
Common (CM1, CM2 and CM3) terminal. Connect remaining end of resistors to 24Vdc +/-5%.

5

Connect each normally open (NO1, NO2 and NO3) terminal to 24Vdc Return.

Apply a calibrated input near the high limit of the selected input configuration. Verify that the
input as reported by viewing the display matches what is expected. Also using a voltmeter,
measure the voltage across each of the normally open (NO1, NO2 and NO3) and common
(CM1, CM2 and CM3) terminals. Verify that the measured voltages across NO1 & NO3 is

6

(CM1, CM2 and CM3) terminals. Verify that the measured voltages across NO1 is between

22.8 and 25.2V and NO2 & NO3 are less than 0.1V.

Disconnect wire connected input COM terminal. Verify that the fault is reported on display and

8

Fault LED turns red. Also using voltmeter, measure the voltage across NO3 and CM3. Verify
that the measured voltage across NO3 and CM3 is between 22.8 and 25.2V.

Remove connection to each normally open (NO1, NO2 and NO3) terminal to 24Vdc Return and

9

connect each normally closed (NC1, NC2 and NC3) terminal to 24Vdc Return.

Apply a calibrated input near the high limit of the selected input configuration. Verify that the
input as reported by viewing the display matches what is expected. Also using a voltmeter,
measure the voltage across each of the normally closed (NC1, NC2 and NC3) and common

10

(CM1, CM2 and CM3) terminals. Verify that the measured voltages across NC1 & NC3 are
between 22.8 and 25.2V and NC2 is less than 0.1V.

Apply a calibrated input near the low limit of the selected input configuration. Verify that the
input as reported by viewing the display matches what is expected. Also using a voltmeter,
measure the voltage across each of the normally closed (NC1, NC2 and NC3) and common

11

(CM1, CM2 and CM3) terminals. Verify that the measured voltages across NC1 is less than

0.1V and NC2 & NC3 are between 22.8 and 25.2V.

Disconnect wire connected input COM terminal. Verify that the fault is reported on display and
Fault LED turns red. Also using voltmeter, measure the voltage across NC3 and CM3. Verify
that the measured voltage across NC3 and CM3 is less than 0.1V

12

This test completes the full test for failures in the input connections to the A/D converter near the low limit
operation and fault conditions. This also covers the CPU, A/D clocks and each relay and for issues in the
relay to output connections.

13

Restore the STA to its original configuration

14

Section 8 - Applications

The following are examples of typical STA congurations.

High Integrity Alarm Trip

The conguration shown in Figure 8.1. o󰀨ers the highest trip integrity. Since the trip and fault
relays are wired in series, any trip alarm or STA fault will trip the nal element or logic solver.
However this conguration is vulnerable to spurious trips as STA safe failures will also trip the
nal element.

High Availability Architecture

The configuration shown in Figure 8.2. offers higher system availability. The Fault alarm is wired

separately to inform the safety system that there is a fault alarm and that this component’s ability

to carry out its portion of Safety Instrumented Function cannot be performed. This configuration

can be used in applications where it is safe to keep the process running for a short time while

a defective instrument is repaired, however this configuration will NOT trip if an STA fault is

diagnosed.

This type of conguration must be used with care in a safety system. The end user must
determine how long the process is allowed to continue after a STA fault is detected and ensure

that the unit can be repaired or replaced within this time.

1oo2 Redundant Architecture

In this architecture, every component appears twice, and may be applicable for use in SIS
systems up to SIL 3 (Figure 8.3). Advantages are improved reliability of trip action and reduced
vulnerability to a single failure compared to a 1oo1 architecture. The logic in this conguration is
an ‘OR’ statement for the safety function; if either sensor input reaches a trip condition or a fault
relay is activated, the loop or function will reach a tripped state.

Analog Output in the Safety Path

When the Analog Output is used in the safety path, the fault alarm must also be monitored to
detect STA failures. In Figure 8.4 below, the fault alarm is wired separately in a high availability
architecture. The fault alarm can also be wired in series with the Analog Output to provide a high

integrity architecture..

Note: When power is lost the AO will fail low. For this reason in a safety application, the logic
solver must be either congured to detect a ‘fail low’ condition (anything less than 4.0mA is
detected as a fault) or ‘fail windowed’ condition (anything outside the 4-20mA range is detected

as a fault).

Note: For STA units with V1.3 rmware or greater, the AO can be used in the safety path.

High Integrity Analog Output

The conguration shown in Figure 8.5. o󰀨ers the highest AO integrity. Any input or STA fault will
drive the AO signal out of range. However this conguration is vulnerable to spurious trips as
STA safe failures will also drive the AO signal out of range.

To return equipment to Moore Industries for repair, follow these four steps:

1. Call Moore Industries and request a Returned Material Authorization (RMA) number.

Warranty Repair –

If you are unsure if your unit is still under warranty, we can use the unit’s serial number to verify the warranty status for you

over the phone. Be sure to include the RMA number on all documentation.

Non-Warranty Repair –

If your unit is out of warranty, be prepared to give us a Purchase Order number when you call. In most cases, we will be

able to quote you the repair costs at that time. The repair price you are quoted will be a “Not To Exceed” price, which means

that the actual repair costs may be less than the quote. Be sure to include the RMA number on all documentation.

2. Provide us with the following documentation:

a) A note listing the symptoms that indicate the unit needs repair

b) Complete shipping information for return of the equipment after repair

c) The name and phone number of the person to contact if questions arise at the factory

3. Use sufficient packing material and carefully pack the equipment in a sturdy shipping container.

4. Ship the equipment to the Moore Industries location nearest you.

The returned equipment will be inspected and tested at the factory. A Moore Industries representative will contact the person
designated on your documentation if more information is needed. The repaired equipment, or its replacement, will be returned to

you in accordance with the shipping instructions furnished in your documentation.
