STA

Programmable Current/Voltage
Safety Trip Alarm

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.

This manual contains all of the information needed to
confi gure, install, operate and maintain this product.
When the STA is used in a SIL rated safety application
(as defi ned by IEC 61508), the Safety Instrumented
Systems section of this manual must be read and
followed in order for the STA to meet it’s IEC 61508
certifi cation requirements.

About this Manual

Wherever you see a “Note”, “ Caution” or “WARNING”
pay particular attention.

WARNING - Hazardous procedure or condition that
could injure the operator.

Caution - Hazardous procedure or condition that
could damage or destroy the unit.

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 is confi gured using front panel push
buttons and a confi guration can also be saved and
downloaded using the PC transfer utility. A large
5-digit display shows menu prompts during push
button confi guration and process variable and status
messages during normal operation.

Inputs

The STA (HLPRG) supports either current inputs from
0-50mA (1mA minimum span) or voltage inputs from
0-10V (250mV minimum span). These inputs can be
trimmed and scaled, refer to the Confi guring Inputs
section of this manual for additional information.

TX Power

A transmitter excitation power supply (24Vdc
±10%@24mA) is standard on the STA (HLPRG). You
may access this externally at the terminals shown in
Figure 5.

Note - Information that is helpful for a procedure,
condition, or operation of the unit.

Model and Serial Numbers

Moore Industries uses a system of model and serial
numbers to keep track of all of the information on
every unit it sells and services. If a problem occurs
with your STA, check for a tag affi xed to the unit
listing these numbers. Supply the Customer Support
representative with this information when calling.

STA Description

Moore Industries’ STA (HLPRG) is a programmable
current/voltage safety trip alarm.

The STA monitors a process variable and provides
two fully user-confi gurable 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.

Alarms

The STA has three (-3PRG) contact closure alarms.
One relay is factory confi gured as a Fault alarm and
the remaining two relays are user-confi gurable 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
confi guration faults will clear automatically once the
confi guration is valid. Input faults can be cleared by
the “RESET FAULT” menu, and self-diagnosed faults
can only be cleared by power cycling the unit. For
more information refer to the Diagnostics and Fault
Alarm section.

The Trip alarms are confi gurable 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.

STA

Programmable Current/Voltage

Safety Trip Alarm

The relay outputs have a 3A@250Vac or 3A@30Vdc,
50/60Hz non-inductive contact rating. The contact
arrangement is SPDT. All outputs are fail safe and
will de-energize to trip (DET) with NO & NC relay
contacts.

Refer to the Alarm Terminology and Confi guring
the Alarms sections of this manual for additional
information.

Options Analog Output (-AO)

The Analog Output can be confi gured to provide a
voltage (0-10V) or current (0-20mA) output. The
current output can be sink or source. Refer to the
Confi guring the Analog Output section of this manual
for additional information.

Note:

The Analog Output is not part of the safety path in

the STA.

Confi guration

The STA can be confi gured from either the front panel
keyboard or by downloading a proven confi guration
using the PC Transfer Utility.

STA Application Examples

The following are examples of typical STA
confi gurations.

This confi guration (Figure 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 confi guration can be used in
applications where it is safe to keep the process
running for a short time while a defective instrument
is repaired. The output process trip relays are
connected 1oo2 to trip providing security against a
single relay failure, however this confi guration will
NOT trip if an STA fault is diagnosed.

This type of confi 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.

ALARM

This confi guration (Figure 1) offers the highest trip
integr

ity. Since all three relays are wired in series,
any trip alarm or STA fault will trip the fi nal element
or logic solver. This provides security against one
process relay failure and any unit failures. However
this confi guration is vulnerable to spurious trips as
STA safe failures will also trip the fi nal element.

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 3 illustrates the way
the STA alarms operate.

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

Figure 3. How Alarms Work with the Process Input

RESET

LOW ALARM

TRIP POINT

DEADBAND

TIME

IN NON-ALARM

DEADBAND

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 buffer zone or
dead band around the trip point to allow for minute
fl uctuations in the process input. In the STA, the
reset point is determined by the dead band 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 Dead band is the range in which an alarm
remains tripped even after the process input has
returned to or passed the trip point. Dead band is not
required. When it is not incorporated into an alarm
application, the trip point and reset point are the
same. The dead band of the STA is set by the user.

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 (infi 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.

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 7.

Internal diagnostics

On power up the unit runs through a thorough
diagnostic test (RAM and ROM TEST messages are
displayed) and an initialization process (SYS INIT
is displayed) 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.

All internal diagnostic faults are latched on the fault
alarm relay. The fault alarm must be cleared by power
cycling the unit. If a fault is still present on power
up then please contact Customer Service for further
assistance.

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).
See Confi guring the Input for more information.

WARNING:

For high level inputs, if Lower Range value is set to
0(V/mA) then brok

the safety function is invalidated.

All input faults are latched on the fault alarm relay.
The fault alarm can be cleared by fi rst clearing the
input failure and then using the confi guration menus
to reset faults. 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).

en wire detection is disabled and

Note:

The trip alarms are independent from the

fault alarms and will be unaffected by the fault

alarms (however they may be affected by the

specifi c failure in the unit).

Confi guration diagnostics

On power up the stored confi 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 confi guration (FCTRY CONFG selection in the
options menu), then confi gure as appropriate for the
application.

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

Note:

The trip alarms are independent from the

fault alarm and will be unaffected 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. For broken wire detection,

this only applies if the input is immediately

broken. If there is degradation present such

that on the way to being broken, the input

(current or voltage) enters the region between

the low alarm trip point and the broken wire

level, the low trip alarm WILL be tripped.

(Slow degradation is characterized by events

that occur over a span of a second or so)

Security Settings

The password security function of the STA is
controlled by a single jumper inside the top of the
unit housing. You will need to remove the top cover
in order to access the jumper. The password jumper
setting will default to Password Required (Pins 1
and 2).

The default security password is 1. This is valid until
the password is changed to another value.

Password Setting

The STA can operate in one of three password modes.

Full Access (Security Jumper set to Pins
2 and 3)– Complete access to the STA confi guration

menu is permitted with no password required for any
read or write operations.

Figure 6. Setting the Internal Jumper for Password Security ON or OFF

Password Required (Security Jumper set to
Pins 1 and 2)– A one to four-digit access code is

required to gain access to the STA confi guration
menu. If the correct code is entered, full read and
write operation is permitted. If an incorrect code is
entered, “WRONG PASWD” will appear for 3 seconds,
and return user to View menu, with read-only access
to the View menu (see Figure 7).

No Access (Security Jumper removed)– The user

is limited to read-only access to the View menu.
“SYS LOCK” will appear if user attempts to enter Main
menu by entering “SEL”. Enter “SEL” a second time to
return to View Menu.

Note:

These security settings are only applicable to

access via the front panel pushbuttons. Security

can be bypassed using the Transfer Utility Software.

STA Confi guration

The STA (HLPRG) operating parameters are set using
the pushbuttons found on the instrument’s front panel.
This section describes the steps in order to confi gure
your STA.

There are three pushbuttons on the unit’s front panel;
UP, DOWN and SELECT. Together with the prompts
displayed on the LCD, these are used to access
menus, and to view and change the settings.

Use SELECT as your “Enter” button, to make your
selections.

Use the UP and DOWN buttons to navigate within the
menus.

View Menu

Figure 7 gives an overview of the View menu.

Upon power-up, the STA displays a ‘SYS INIT’
message until the power up self test is complete.
In normal operation the View menu will display the
variable as confi gured. This can be the process
variable, the analog output variable, or both being
toggled (Refer to Confi guring the Options Menu for
more details).

1. From the display, press DOWN.

2. If the -AO option is present, and the unit is
NOT confi gured to toggle, the other variable
will be displayed. Continue pressing DOWN
to view the Analog output zero, Analog output
full, trip point (AL1), trip point (AL2) and fi nally
returning to display measured value.

3. Enter Main Menu at any point by pressing
SELECT.

Note:

If the Security jumper is removed (see Figure 7.)

entering SELECT will cause “SYS LOCK” to appear

if user attempts to enter Main menu.

Under fault conditions, the STA will display the error
message describing the fault (see Table 7 for list of
messages) which can be cleared from the Reset Fault
menu or by power cycling the unit.

Figure 9 gives an overview of the Main Confi guration
menu.

Upon power-up, the STA displays the variable(s) as
confi gured via the Confi gure Options menu. Pressing
the SEL button accesses a series of displays that
show, in succession, the settings currently stored in
unit memory.

Depending upon whether or not the Security Jumper
has been installed (Figure 6), pressing SELECT will
access either the fi rst screen in the main confi guration
menu, “CONFG INPUT”, the password code query
screen, “ENTER PASS” or the “SYS LOCK” screen.

Once the Main Menu has been accessed, the DOWN
button is used to move through all of the sub-menus
in a loop. Pressing the SELECT button accesses the
fi rst screen of the sub-menu shown on the LCD.

Note:

STA is programmed to time out from the

confi guration menu after 5 minutes of inactivity.

When trimming the unit, 30 minutes of inactivity are

allowed before the time out. If the unit times out, the

previous settings will be reapplied.

3. If you have entered the correct password, the
sensor confi guration menu, “CONFG INPUT”,
will be accessed. If not, the display will show a
“WRONG PASS” message.

4. From “WRONG PASS”, wait three seconds to
go back to the View menu. Use the UP and
DOWN buttons to view the settings in the View
menu.

Note:

The menu to set or change the password stored

in STA memory is detailed in the Password

Confi guration section of the manual.

Scaling the Input

Figure 10 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 Current input would
then produce a PV displayed in mA.

Also known as “Smart Ranging”, scaling of the STA
(TPRG) 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 calibration
equipment.

1. At the “SCALE INPUT” display, press SELECT.

2. “SCALE MODE” appears; press SELECT.
Choose whether or not to enable scaling. This
will be confi gured in the next menu. Select
“SCALE OFF” or “SCALE ON” and press

SELECT.

Scale Mode– This allows you to customize

your display for your application. For example,
if your process is sending a 6mA-17mA
reading to the STA and you wish to view
the input as 0-100% then this can be
accomplished with the Scale Mode feature.

3. The “SCALE EGU” prompt is brought up.
Press SELECT and choose the desired fi ve
character string to be displayed. While editing
the string, the current position being edited
will be alternated with a “^” character. Use the
UP and DOWN button to select the correct
character. Pressing SELECT will move to the
next position.

If you selected “SCALE OFF” in the “SCALE
MODE” menu, the menu skips to Step 6. If you
selected “SCALE ON”, proceed to Step 4.

5. “SCALE FULL” appears. Press SELECT to
enter the menu. Enter the value you wish as
your full scaled range. This value will appear
when you are at the full end of your range.
Press SELECT.

6. “EXIT SCALE” appears. If all scaling
parameters have been set, press SELECT.
The next menu selection to appear is “TRIM

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 confi guration
upon power-up. If there are problems with the unit, or
with confl icting 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.
Table 7 provides a full list of diagnostic messages and
corrective actions.

7. If “ERROR UNDO” is selected, you will be
returned to View menu and no changes will
be applied to unit (previous confi guration will
remain unchanged).

Installation

Installation consists of physically mounting the unit
and completing the electrical connections.

Mounting

The STA is housed in a “universal” DIN case that can
be mounted on both 35mm G-type (EN50035) and
35mm Top-Hat (EN50022) DIN-rail.

To mount the STA on a Top-Hat DIN-rail, seat the
upper extrusion on the unit back panel over the top lip
of the rail and pivot downward until the housing locks
into place.

To mount the unit on a G-type rail, seat the extrusion
under the top lip of the rail and again, pivot downward.

When mounting multiple units, like a rack or cabinet,
make sure to allow adequate vertical spacing for
pivoting the units.

Making the Electrical Connections

Refer to Figure 5 (STA Front Panel Confi guration)
and Figure 21 (STA connected to PC) for electrical
connections.

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.

CE Conformity

Installation of any Moore Industries’ products that
carry the CE certifi cation must adhere to the
guidelines as stated in order to meet the requirements
set forth in the European EMC and Low Voltage
Directives (EN 61326 and EN 61010). Consult the
factory for the most current information on products
that have been CE certifi ed.

Operation

Once confi gured, installed, and supplied with the
correct power, the STA alarm begins to operate
immediately. Depending upon environmental
conditions, it can be expected to operate unattended
for extended periods of time.

Maintenance

Moore Industries suggests a quick check for terminal
tightness and general unit condition every 6-8
months. Always adhere to any site requirements for
programmed maintenance.

Customer Support

STA

Programmable Current/Voltage
Safety Trip Alarm

STA in Safety Instrumented Systems

The STA is designed for use as a component part of a
safety instrumented system as defi ned by
IEC61508-4 para 3.4.1.

This user manual contains all of the information
needed to confi 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 certifi ed, by TUV Rhineland
Industries Service GmBH, to IEC 61508 for a single
use safety instrumented device up to SIL 2. In
addition, the fi rmware of the STA, during the above
review, was determine to have measures in place
to address systematic errors up to SIL 3. As such,
this allows the STA, when confi gured in a redundant
system architecture (1oo2, 2oo3, etc), to achieve up
to SIL 3 as described in IEC 61508-3.

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.

Confi guration

The unit can be confi gured using the front panel
buttons or transfer utility as described in this manual.

Note:

While the system is in confi guration mode the

system is in an offl ine mode and is not performing

the safety function

Do not attempt to connect the STA Transfer Utility
cab

le to the STA while the output relays are

connected to a load.

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

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 merely alarm the fault while
maintaining the process in normal operation. Refer to
Figures 1 and 2 for typical STA confi gurations.

Separating the process and fault loads increases
availability but its use must be authorized only after a
careful hazard and operability study involving suitably
qualifi ed persons.

WARNING

With this confi guration, an internal STA fault would not trip

the EUC

.

Product life

The product life of the STA is 50 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 fi 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 specifi cations table of this user manual
for ambient conditions and required power input.

34 The Interface Solution Experts

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 effect must be capable of performing its
specifi 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.

Analog Output - Non Safety

The STA may optionally be provided with an analog
output which can be used for connecting to displays,
control systems, etc. The STA analog output is NOT

designed 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 certifi ed safety
function of the STA.

STA

Programmable Current/Voltage

Safety Trip Alarm

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.

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

F

or 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.

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

A proof test interval of 3 years is recommended for
a single STA used in a typical SIL 2 low demand
application (15% of the SIL band being allocated to
the STA at 40°C ambient).

The proof tests described in Table 9 are designed to
cover all possible dangerous undetected faults that
can be detected without opening the unit. Periodically
testing the STA, using the proof test steps outlined
below, the accumulated PFD
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.

AVG value can be reduced

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 will always be latched.

Remote Manual Reset – Procedural Issues

The STA has a facility for the connection of a remote
switch to release the latch on the outputs.

This function is meaningful only when automatic
latching of outputs is selected in the confi 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.

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 World Headquarters in
North Hills, CA U.S.A for repair and refurbishment
(refer to Returns Procedures at the end of this
manual).

The STA is a certifi ed Safety component. Repair or
replacement of any component without authorization
from Moore Industries will invalidate any remaining
warranty and the IEC61508 certifi 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 classifi 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 confi dence
in the FMEDA analysis of dangerous failure rates.
Please ensure that any components returned to
Moore Industries Inc are returned with a clear report
identifying the fault experienced.
