* N/R — Not recommended. Connecting 4 equivalent loads to a three phase source in
delta configuration will create an unbalanced load. It’s usually more feasible to run a sepa-
rate #10 AWG line directly to the 4th module.

What are the CSA and NRTL?
CSA (Canadian Standards Association also known as CSA International) was established in 1919 as
an independent testing laboratory in Canada. CSA received its recognition as an NRTL (Nationally
Recognized Testing Laboratory) in 1992 from OSHA (Occupational Safety and Health Administration) in
the United States of America (Docket No. NRTL-2-92). This was expanded and renewed in 1997, 1999,
and 2001. The specic notications were posted on OSHA’s ofcial website as follows:
Federal Register #: 59:40602 - 40609 [08/09/1994]
Federal Register #: 64:60240 - 60241 [11/04/1999]
Federal Register #: 66:35271 - 35278 [07/03/2001]
When these marks appear with the indicator “C and US” or “NRTL/C” it means that the product is
certied for both the US and Canadian markets, to the applicable US and Canadian standards. (1)
Argus rectier and power system products, bearing the aforementioned CSA marks, are
certied to CSA C22.2 No. 950 and UL 1950, or CSA/UL 60950.
As part of the reciprocal, US/Canada agreement regarding testing laboratories, the Standards Council
of Canada (Canada’s national accreditation body) granted Underwriters Laboratories (UL) authority to
certify products for sale in Canada. (2)
Only Underwriters Laboratories may grant a licence for the use of this mark, which indicates compliance
with both Canadian and US requirements. (3)
What are NRTLs and what do they do?
NRTLs are third party organizations recognized by OSHA, US Department of Labor, under the NRTL
program.
The testing and certications are based on product safety standards developed by US based standards
developing organizations and are often issued by the American National Standards Institute (ANSI). (4)
The NRTL determines that a product meets the requirements of an appropriate consensus-based
product safety standard either by successfully testing the product itself, or by verifying that a contract
laboratory has done so, and the NRTL certies that the product meets the requirements of the product
safety standard. (4)
When was the NRTL started and who governs it?
In 1983, in a suit brought on by an independent testing laboratory, OSHA was court ordered to remove
specic references to UL (Underwriters Laboratories) and FMRC (Factory Mutual Research Corporation)
from its regulations.
In 1988, OSHA revised its regulations to remove those references and the NRTL program was
established.
The NRTL Program is both national and international in scope with foreign labs permitted.

EXPLANATION:
The market shift from vented or “wet cell” to valve regulated lead acid (VLRA) batteries has prompted Argus to
update its factory default settings to accomodate the requirements of these batteries.
The changes listed below are being implemented immediately as new factory default settings in all Argus power
products. However, as always, customer requested settings will take precedent over factory defaults.
This addendum is to accompany all new Argus user manuals. Questions about the new factory default settings
should be directed to our toll free 1-888-GO ARGUS Technical Support line.

2.1 Introduction
Please read this manual thoroughly prior to use in order to become familiar with the unit's numerous
features and operating procedures. To obtain a maximum degree of safety, follow the prescribed
sequences as outlined.
This manual incorporates warnings and notes to the user. Points that are vital to the proper opera-
tion or safety of the operator are indicated by the heading: WARNING. Points that are important to
the performance or ease of use of the equipment are covered by a notation that is double under-
lined.
Items that refer to physical components or features such as indicator lights will be in Bold Italic
typeface. Items that refer to states or modes and generated messages such as found on the LCD
display panel will be in BOLD UPPERCASE typeface.
2.2 ARGUS Numbering system
ARGUS technologies uses a eight digit drawing number system which is broken into three blocks.
The first three digits describe the category of the product ie. rectifier or fuse panel. The next three
digits indicate the sequence in which the product number was allocated in a particular category.
The last two digits indicate the type of drawing ie:
05 .................Schematic
06..................Outline Drawing
20 .................Main Assembly
ARGUS Technologies uses a eight digit part numbering system for all components and sub assem-
blies. Each part is covered by its own unique number. Due to the quantity categories will not be
listed within this manual.

3.0 General
3.1 Scope
This instruction manual covers the installation, and operation of Argus Technologies' RSM 48/100
switched mode rectifier.
3.2 Introduction
The RSM series of rectifiers employs a high frequency switched mode conversion technique to pro-
vide a fully regulated and isolated DC output from the A.C. mains. The unit provides external con-
nections for input, output and alarm interfaces. The 48 volt rectifiers are used in a positive ground
configuration only. The units are fully functional battery eliminators and therefore do not require an
external battery to meet the performance requirements as outlined in the specification section of this
manual.
3.3 Features
The following sections (3.3.01 through 3.3.32) will cover the various features available on the RSM
48/100 Rectifier.
3.3.01 LCD Display and Control Keys
Located on the front panel of the unit is a 2 row by 16 character LCD display. All of the unit's oper-
ating parameters, status and alarms can be viewed with this display See Figure #1 for a detail of a
normal display. Normally, the display indicates:
- Output current of the module
- Output voltage of the module
- Float/ Equalize /Test Mode Status
- Current limit or soft start indication
- Corporate identification, Module Serial #
NOTE: The front panel may be powered up for up to 20 seconds after all power (input and output)
is removed from the unit.
Float, equalize, soft start, current limit and test mode status designators pulsate to differentiate
them from the output voltage and current readings. The serial number is displayed with normal
mode, & alarm mode messages. The corporate identity is displayed only during normal operation.
Please see Figure #3 and Table #1 for the complete menu tree and display messages possible.
Possible alarm messages are referenced in the minor alarm section. The display is updated two to
three times per second. Output voltage and current are displayed on the top line under all modes of
operation. Current readings are accurate to within 2% while voltage measurements are accurate to
0.2%. Sensing for voltage and current measurements is present before the output breaker of the
module. Therefore only the true output of the rectifier is displayed. Refer to Figure #14 when per-
forming adjustments in order to see how the front panel message display changes when accepting
input.
There are three control buttons on the front panel and are labelled with an up arrow, down arrow,
and a curved arrow. The first two (ADJUST/SCROLL) are used to scroll thru a list of items in for-
ward and reverse order, and the last button (ENTER/SELECT) is used to select the displayed item.
Initially the ADJUST/SCROLL buttons allow the user to change the display from its normal Volt-
age/Current/Alarms mode (NORMAL) to one of STATUS, ADJUSTMENTS, REMOTE COMMUNI-
CATIONS,orTEST MODE and the third button is used to switch between FLOAT and EQUALIZE
modes when the display is in the NORMAL mode.

(NOTE: View hole may or may not be present)

The display is back-lit any time a control key is depressed or when the unit first starts up. The dura-
tion of back-lighting is programmed during setup. The viewing angle of the display is changed by
one of two methods. If there is a small hole below the VIEW label, then a small screwdriver or
tweaker is used to adjust the viewing angle. If there is no hole, then the viewing angle is adjusted
by pressing and holding the ENTER/SELECT button, and pressing the right SCROLL/ADJUST but-
ton (labelled with an upwards arrow). The viewing angle can then be adjust by pressing either
SCROLL/ADJUST button repeatedly and then pressing the ENTER/SELECT button to return to
NORMAL mode.
Due the limited number of characters that can be displayed, abbreviated messages are used. The
manual uses both abbreviated and complete condition descriptions. See Table #1 for display mes-
sage abbreviations.

3.3.02 Status Mode Indicators
The indicators provide visual indication of operational status and alarms. The conditions and associ-
ated colors are:
Module Status - OK ......................Green
Module Status - Micro-Controller fail/reset .....Red
Module Status - Alarm Condition Present .....Yellow
Module Fail.............................Red
Note that the Red Module Status - Micro-Controller fail/reset indicator is located behind the
frosted panel between the Green Module Status - OK and Yellow Module Status - Alarm Condi-
tion Present indicators and is normally not visible.
3.3.03 Status Indicator - Module OK
When both circuit breakers are closed and no alarm conditions are present the Module Ok indicator
will light. The indicator will not illuminate if a local operator is adjusting or interrogating the unit. Re-
mote or local access of module status does not affect module status. Remote adjustments will af-
fect the indicator.
3.3.04 Status Indicator - Alarm Condition Present
Any alarm condition will cause the Alarm Condition Present indicator to illuminate. Local adjust-
ment or entry into some of the menu modes (except status mode) will cause the LED to illuminate.
The indicator will continue to illuminate any time the criteria is meet and an external voltage is pres-
ent at the modules output. The indicator will not function if the micro-controller fails or is in reset.
Associated with the indicator is a minor alarm contact on the equipment shelf. A minor alarm condi-
tion on any module in a shelf will cause the relay to energize.
3.3.05 Status Indicator - Micro-Controller Fail / Reset
Located in between the Module Status - Ok and Alarm Condition Present indicators is a sepa-
rate Microcontroller Fail/Reset indicator to illuminate in the unlikely event that the micro-controller
fails. Failure of the micro-controller to respond to a watch-dog timer triggers the alarm. The LCD will
be suppressed during this mode of failure. The minor alarm contact at the shelf level will energize in
the event of a micro-controller failure on one of the modules. The indicator will continue to illuminate
any time the criteria is met and an external voltage is present at the module's output.
3.3.06 Module Fail Indicator
Located to the right of the status indicators is a separate Module Fail indicator. If any of the condi-
tions defined as a module failure (see True Module Fail Alarm) occur the indicator will illuminate.
The module fail relay is de-energized while the indicator is on. The indicator will continue to illumi-
nate any time the criteria is met and an external voltage is present at the module's output.
3.3.07 Float Mode
Normal operation of the module is in the FLOAT mode. The module will default to this mode when
A.C. power is supplied to the unit. When in the FLOAT mode the output voltage of the module is
determined by the FLOAT VOLTAGE setting found in the submenu ADJUSTMENTS. The
Float/Equalize mode control button (labelled Enter/Select) manually returns the unit to the FLOAT
mode from a locally initiated EQUALIZE.FLOAT mode is indicated by illumination of the FL beside
the output voltage reading on the LCD display. The level is protected by fail safe circuitry in the un-
likely event of micro-controller failure.
