1. INTRODUCTION

1.2 The CFR Advantage

ADVANCED POWER PROTECTION TECHNOLOGY

Power protection devices can be judged b y the type and quality of power
they provide. Alpha CFR Uninterr uptible Power Supplies provide continuous,
conditioned “computer-grade” AC power to electronic equipment such as Computer
Systems, Point of Sale Terminals, Process Controls, Telecommunications, Cable
TV Headend, Broadband LAN, Manufacturing Control Systems, Critical Care and
Hospital Lab Equipment.

SURGE AND SPIKE REJECTION

Alpha's proven design virtually eliminates surges and spikes. The Alpha
CFR UPS provides spike attenuation of 2000 to 1 and meets the requirements of
IEEE 587 / ANSI 62.41.

REGULATION

Unlike many standby power systems, which regulate output voltage
only when operating from their battery backup, the Alpha CFR UPS
constantly maintains + 1% output regulation without using precious battery power.
Even with input voltage fluctuations as great as +10% or -25%, the output remains
constant, regardless of load.

ISOLATION

Electromagnetic and Radio Frequency Interference (EMI and RFI) can
damage semiconductors and have devastating effects on critical data. The CFR
UPS input is
this type of interference. Measured in decibels (dB) of attenuation, Alpha's CFR
achieves up to 120 dB common mode, and 60 dB normal mode.

totally isolated

from the output to provide maximum protection from

EXTENDED BACKUP CAPABILITY

Alpha's EBP Series External Batter y Packs allow you to greatly extend
your backup capabilities and power through long utility outages. Completely self­contained and pre-wired, simply plug the EBP cabinet into your CFR and forget
about it. EBP Series External Battery Packs can also be ordered with an optional,
external charger to greatly reduce battery recharge times.

providing you with a variety of interface options.

SELF-TEST CAPABILITIES

The CFR has a built-in, self-test function that checks all critical areas of
the UPS, including the batteries, to ensure optimum performance. Whenever a
problem is detected, the UPS lights a “Service” indicator. Self-test is extremely
useful during troubleshooting and maintenance.

PRECISE LOAD AND OVERLOAD INFORMATION

The Alpha CFR provides vital load information to eliminate guess work
associated with matching the appropriate load to your unit. The Alpha CFR displays
the existing load, and whenever the load exceeds the rated output, an "Overload"
indicator is illuminated.

GENERATOR READY

The CFR UPS is equipped with a frequency sense circuit, along with a
constant slew frequency synchronization circuit, to provide trouble-free operation
with most standby generators.

SAFETY

Designed to meet or exceed the safety standards established by UL,
CSA and VDE, the Alpha CFR UPS is one of the saf est, most reliable and versatile
uninterruptible power supplies available. Our commitment to safety and quality
engineering has not only established industry-wide safety standards, but has earned
Alpha Technologies international recognition as a leader in power protection
equipment.

SID equipped units can be connected to an external modem. A shielded
null-modem serial cable, DE-9 male to DB-25 male, is required to connect the
external modem to CFR. The most common ways to connect are by using one of
the following cable/adapter sets:

1. A null-modem cable with DE-9 male to DB-25 male ends (shown below).

2. A null-modem cable with DB-25 male to DB-25 male ends and a 9-25 adapter.
3 . A standard “straight-through” cable with DE-9 male to DB-25 female and a null-

modem adapter which has the TX and RX swapped in the adapter .

These cables and adapters are a v ailable commercially. Fig. 10 sho ws the
minimum set of connections required for making a null-modem cable. See Section
“4.2 External Modem Configuration” to configure the modem and CFR.

3. INSTALLATION

3.1 Pre-Installation

Do not connect the CFR UPS to a line conditioner, isolation transformer or
any other similar type of device. Damage to the CFR UPS and the line
conditioning equipment can occur.

Site Preparation

The UPS should be installed upright in a well-ventilated, dust free
environment. The weight of the UPS, especially if it has an optional battery pack,
is quite heavy (see specifications). Do not place the unit on any surface unable to
fully support its weight.

Utility Circuit Breaker

The UPS should be installed on a dedicated circuit with a properly sized
circuit breaker. Breaker size can be determined by adding 15% to the maximum
input current of the unit (see specifications). For example, the CFR 1500 draws

11.9 Amps of current when configured at 120VAC. By adding 15%, the number
becomes 13.7 Amps. In this case, a standard 15 Amp circuit breaker is suitable
for use.

Grounding

Since the CFR UPS bonds output neutral to ground (qualifying it as a
"separately-derived power source"), proper grounding is critical. Many older facilities
may have an electrical system that is incapab le of supporting this type of grounding
requirement. To ensure optimum performance from your UPS, always install a
hardwired ground. A qualified electrician should also inspect the existing wiring in
the building prior to installation to verify proper grounding.

Standby Generators

The CFR is equipped with a frequency sense circuit, along with a constant
slew frequency synchronization circuit, to optimize operation with most standby
generators. Prior to installation, compare the output voltage of the generator to the
voltage requirements of the UPS (see CFR nameplate label). If the UPS requires
240 V AC input and the generator produces only 208 V A C , it will cause the UPS to
run continuously off of battery power . This w ould discharge the UPS batteries and
cause the output to fail.

Alpha Technologies recommends using a generator equipped with an
electronic speed and voltage control. If a generator equipped with a mechanical
governor "speed control" is used, this could also cause the UPS to run continuously
in LINE FAILURE mode due to the unstable frequency of the generator.

3. INSTALLATION

3.2 Connecting the CFR (Plug and receptacle)

CAUTION: Installation and wiring should be performed by qualified service

personnel in accordance with applicable electrical codes. Ver ify that the
main utility panel is switched off before proceeding. Mark all circuit breakers
supplying the UPS.

1. Connect a dedicated ground wire from the GROUND lug on the back of the CFR

to an electrical ground point (i.e., wall receptacle gound or a copper water pipe).
The wire size must be at least 14 AWG (2.0 mm
and have green insulation provided with one or more yellow stripes.

NOTE: Most electrical codes require this type of ground connection in
case the AC Line power cord is disconnected from the wall. Always consult
your local electrical code to ensure prescribed grounding practices.

2. Connect the CFR’s A C power cord to the receptacle.

3. If using an external battery pack, plug its connector into the rear panel of the

3.4 208 VAC vs 240 VAC (60 Hz) Configurations

In North Amer ica, there are only two recognized supply voltages: 208
VAC (most commonly used in industrial, commercial, and office areas); and 240
VAC (most commonly used in residential areas). 120 VAC can be derived from
both 208 and 240 VA C services.

NOTE: The ter ms 220 VAC and 230 VAC are actually local terminology,
referr ing to 240 VAC service.

LOAD SHARING

If several pieces of equipment are connected to the 120 V output of the
CFR (either to the output receptacle or terminal block), care must be taken to
ensure that the total power drawn does not exceed the maximum rating of the unit.
For Terminal block output, wherever possible, connect all 120V loads to L1 (not
L2). If 120 V loads are connected to L2, do not exceed the current listed in Table

3.4.1.

3. INSTALLATION

3.4 208 VAC vs 240 VAC (60 Hz) Configurations

Since loads are shared, it is possible to exceed the rated maximum output
current of one of the transformer windings, without actually exceeding the rated
output current of the CFR-UPS. Therefore, careful consider ation must be given as
to how the loads connected to the CFR are to be divided.

One way to ensure that the current drawn from each half of the transformer
windings is within the CFR’s specifications would be to measure the actual total
load being drawn. This can be accomplished using a clip-on current probe (ref er to
drawings below). The total current being drawn by L1 is a combination of the
current draw from A + B + C, (where A is the total current draw from each 120V load
connected to the receptacle, B is the total current draw from each 240V load
connected to the receptacle, and C is the total current draw from the L1 side of the
terminal block). The total of these currents must not exceed the rated output
current for each winding of the CFR. The same is true for the L2 winding of the
transformer. You can measure these currents at points B and D, (where B is the
total current draw from each 240V load connected to the receptacle, and D is the
total current draw from the L2 side of the terminal block).

NOTE: If using the SID or IID to measure the output currents, you must
calculate the Output current for L1 as described below.

SID

If the CFR has an
port of the CFR connected to a PC , as OUTPUT CURRENT 1 and Output Current
2 (see section 5.6, Output Parameters). The current drawn in Winding 2 is Output
Current 2. The current dra wn in Winding 1 (Output current L1) is calculated b y
adding Output Current 1 and Output Current 2. The “Overload” light will flash if
the current in either winding is exceeded or , if the total output VA or Watts exceeds
the maximum rating of the UPS.

4. OPERATION

4.2 External Modem Configuration,

Configuring the modem to work with CFR

The CFR uses a three wire interface (RX, TX, and GND) to communicate
with the modem; no other hardware handshaking lines are used. The modem m ust
be configured correctly to work with the CFR. To configure the modem, set the
modem DIP switches as explained below:

Switch Option

1 Set modem to ignore DTR (DTR override)
2 Set modem to generate verbal (not numeric) results
3 Set modem to generate result codes
4 Disable echoing of commands (Echo suppressed)
5 Disable auto answer
6 Set modem to set CD when it connects
7 Set modem to load factory setting on power-up
8 Set modem to recognize AT commands (smart mode)

NOTE: Do not enab le auto ans wer using DIP s witches. CFR sends an AT command
to control the auto answer mode (either “A TS0=1” or “ATS0=0”).

The modem initialization string is a set of commands that CFR sends to the
modem to initialize it. For a USRobotics or compatible modem, include the following
AT commands in the initialization string:

X4 Extended set of result codes

Q0 Result codes are displayed

V1 Display verbal (words not numbers) result codes

&H0 Disable transmit data flow control

(neither hardware “CTS” nor software “XON/XOFF” flow control)

&R1 Disable hardware receive data flow control

(set modem to ignore RTS and send data all the times)

&I0 Disable software data flow control (no XON/XOFF flow control)

&B1 Set the RS–232 serial port rate to fixed

(set modem to detect the AT command baud rate and maintain it)

The first three commands are supported by all Hayes compatible modems;
however, the last four commands belong to an extended set of Hayes commands
which are supported by USRobotics and some other manufacturers. Therefore, for
USRobotics Sportster family of modems, the proper initialization string is (CFR default
setting):

USRobotics initialization string:

continued

ATX4Q0V1&H0&R1&I0&B1

for other modems that do not support the extended set of Hayes commands you
should compile an equivalent command. Howe ver , in most cases, using the f ollowing
simplified initialization string results in satisfactory operation:

Simplified initialization string for most other modems:

ATQ0V1

NOTE: Do not include the auto answer command in the initialization string. CFR sends

an A T command to control the auto answ er mode (either “ATS0=1” or “ATS0=0”).

31

4. OPERATION

4.3 External Modem Operation

Initializing the Modem

For proper operation, the CFR needs to initialize the modem before using
it. Since a modem may be connected to the CFR at any time, the CFR sends the
modem initialization string repeatedly and at various times:

— One minute after the CFR powers up and then every hour

— At the beginning of a self-test*

— Before sending out the first automatic alarm

— Every 2 minutes after a failed modem command

(dial, hang, or initialize)

— After activating one of the modem options

This guarantees that the modem is initialized before sending out the first
automatic alarm. Even if the modem is disconnected and connected again while
the CFR is in operation, the CFR would re-initialize the modem if the dial command
fails. If you would like to re-initialize the modem at any point, just execute a self­test* and the CFR will send out an initialization string.

One problem scenario is possible: if the modem DIP switches are set for
auto answer and the modem answers an incoming call before being initialized by
the CFR. In this case, the modem will set it’ s o wn RS–232 baud rate to the connection
baud rate, which is most likely not 1200 baud. This results in the CFR not being
able to initialize or talk to the modem. For this reason,
should be configured for no answer. The CFR will initialize the modem for auto
answer , if specified, and set the modem RS-232 baud rate to 1200 by sending an
AT command. This guarantees the two devices are configured to communicate.

the modem DIP switch

Note: when a modem is connected to a running CFR unit and a remote host calls
before the CFR has initialized the modem, the CFR/modem will not answer the
remote call. This is the e xpected beha vior; the modem should not ans wer until the
CFR has initialized it. If immediate access is required, just execute a self-test*
and the CFR will send out an initialization string.

When the initialization command fails, then the CFR assumes the modem
is on line and sends the escape sequence, resets the modem (ATZ), and then re­sends the initialization string. In this wa y, the CFR can initialize the modem under
all circumstances (except when the modem is assuming a different RS–232 baud
rate). If these attempts to send the initialization command fail, the CFR tries the
initialization sequence every two minutes until the modem is initialized.

*To initiate a self-test: press and hold the MANUAL START until test begins; the LINE
FAILURE and TEST lights will be lit for approximately one minute. See section “4.1 Start­up, Test and Shutdown” for more information.

4. OPERATION

4.3 External Modem Operation,

Sending Automatic Alarms

When a power e v ent takes place , the CFR stores it in an event b uff er. The
event buffer can hold up to 7 events. If for some reason the CFR can not send the
events (unit is not connected to a modem, no dial tone, or the host is busy) and the
buffer overflows, the CFR will maintain the most recent 7 events on the buffer.
Once the modem is operating, then the CFR will send all the events in the same
order that they have been received (first-in-first-out buffer).

For sending automatic alarms, the CFR sends the dial command (either
DIAL1 or DIAL2) to the modem and wait up to 60 seconds to obtain a “CONNECT”.
If “CONNECT” is not obtained then the CFR will try again the same dial command
after two minutes (
“NO CARRIER”, “NO DIAL TONE” or “BUSY”). However , if modem does not respond
back at all (
the modem first and then sends the dial command. The CFR tries a dial command
indefinitely (ev ery two minutes) until dialling is successful. Thus, it is possible that
some DIAL2 events will be queued while waiting for a DIAL1 event to get through.

A dial command is successful when modem responds with a “CONNECT”
in less than 60 seconds. After establishing the connection, the CFR sends the
location ID followed by all the event string. If more subsequent events are queued
for the same phone number, the CFR sends them on the same call. The following
is an example of the message sent when the utility line fails:

After sending the event alarm, the CFR drops the connection by sending
the escape sequence, “+++”, follo we d by the hang command, “ATH”.

4. OPERATION

4.3 External Modem Operation,

Remote Access Using External Modem

When the remote access feature is enabled, the CFR sends the auto answer
command “ATS0=1” to the modem at the end of the modem initialization (see
terminal menu 521 in section “5.10 External Modem Parameters”). When a remote
host calls the unit, the CFR’s modem will pick up the call on the first ring and send
a “CONNECT” message to the CFR. When the UPS receives this string it kno ws
a remote call has begun and will stop trying to send any alarms until after the call
is ended.

After establishing the connection, the remote host can access all the RS–
232 menus just as a local terminal can. See section “5. T erminal Communication”
for details. It may be necessary to press the RETURN key to display the first
menu.

If a remote access call is in progress and the remote host drops the
connection, the CFR receives a “NO CARRIER” message from the modem. When
this message is received, the CFR recognizes the call has ended and will resume
sending out any automatic alarms that may have been queued while the remote
call was in progress.

If a remote access call is in progress and no RS–232 commands are
received for more than “Remote Hang up Time,” then the CFR forces modem to
drop the connection by sending the escape sequence, “+++”, followed by the hang
command, “ATH” (see terminal menu “528” in section “5.10 Exter nal Modem
Par ameters”). This pre vents a f aulty remote host from tieing up the telephone line
and preventing any other remote calls to be received or automatic alarms to be
sent out.

4.4 Using the Standard Interface Device

The Standard Interface Device displays vital UPS operating parameters and
has the ability to self-test the UPS at the touch of a button. When used in conjunction
with the CFR's rear-panel “Form-C” contact closures, UPS status information can be
sent directly to a Local Area Network (see section 2.5).

UPS Powering Up

Whenever the CFR is po wering up, the TEST LED flashes for a fe w seconds.
At the same time the OUTPUT LOAD indicator LEDs flash in a chasing pattern to
indicate that there is no output. As soon as the power up sequence is completed,
the TEST LED switches OFF and the OUTPUT LOAD display LEDs show the

Output Shutdown Pending

The TEST LED will flash to indicate that a UPS output shutdown is pending
to occur. When the oper ator gives an output shutdown command (either via the RS­232 serial port or by the LAN Interface port), the UPS delays the shutdown (for a
programmable period) before actually switching off the output.

Output Shutdown In Progress

The five OUTPUT LOAD LEDs will flash in a chasing pattern whenever the
CFR output is switched off by an output shutdown command (either via the RS-232
serial port or by the LAN Interface port). This will also occur when the unit is first

5.1 Remote RS-232 Operation

Introduction

This section of the manual describes ho w to monitor , control and calibrate
the CFR-UPS using RS-232 ASCII commands and how to navigate through the
program using the menu structure.

The RS-232 serial interface is designed to work with terminal emulation
software in an interactive mode. Various parameters and commands may be
accessed either through the menus or by typing the number associated with the
desired functions. See section 5.3.

RS-232 menus have a hierarchical format. The top level menu, which is
also called the OPENING MENU, can be accessed by pressing the ENTER key
(which sends a carriage return character). This men u lists the numbers for accessing
other sub-menus plus displays the current LINE status and pending ALARM
conditions.

The figure below shows the typical opening menu screen which displays
the menu options 1 through 7 followed by status and alarm messages. The INPUT
LINE shows the current status of the AC line which ma y be PRESENT; FAILURE;
or TEST MODE. The ALARMS message lists all current alarms. For a complete
description of alarms refer to section 5.13.

5.4 Menu Commands Overview

Overview

The following section provide a general overview of the menu structure and
give some examples of ho w to perfo rm certain command functions such as testing
the UPS.

Querying CFR Status and Measured Parameters

The current status (mode of operation) of the CFR and all active alarms
are displayed at the end of the opening menu (see section 5.13 for a list of status
messages and alarm events). Press “ENTER” to query CFR status and alarms.
Use commands “1” to “4” to query the battery temperature, input (line) parameters,
output (load) parameters, and battery parameters. Command “0” is a special
command which displays all of the UPS parameters together. This command is
discussed in section 5.12.

Testing the CFR

Use commands “11” and “12” to start and terminate a self-test. During a
self-test, the UPS switches to the inv erter mode to test the battery and the inverter
hardware. The test takes about one min ute and, when complete an ASCII message
is sent to indicate the result. You may also schedule a self-test using commands
“53” to “55”.

Shutting OFF the Inverter to Save Battery

Commands “507” and “508” can be used when the UPS is in the inverter
mode to switch the inverter OFF to prevent a deep batter y discharge during
extended line failures . The CFR UPS s witches to normal oper ation when input line
is restored.

NOTE: Invoking the “507” or “508” command will drop the connected load.

Scheduling Output Shutdown/Reboot

The output of the UPS can be turned OFF by sending a RS-232 command.
Commands “501” to “506” control the output shutdown feature. When the UPS
receives a start shutdown command, “502”, it waits for the period specified in
output shutdown delay, “505”, and then turns OFF the UPS output. The UPS
remains in the shutdown mode for the mandatory down time specified by output

shutdown duration, “506”. Depending upon the setting of the output shutdown
recovery mode, “504”, the output is switched ON when the shutdown duration

expires or when the input is restored. Y ou start a shutdown whenever the shutdown
delay is set using command “501. ” A pending shutdo wn ma y be cancelled by sending
command “503”.

5. RS-232 TERMINAL COMMUNICATION

5.4 Menu Commands Overview

Calibrating the CFR

The CFR UPS may be calibrated using two sets of parameters - Maintenance
Par ameters (commands “70” to “79”) and Service Parameters (commands “80” to
“89”). Maintenance parameters allow you to customize the CFR detection and
warning lev els. There should be no need to change these setting unless wider or
narrower detection tolerances are required.

T ransmitting Unsolicited Alarms

The UPS can automatically transmit alarm messages (in ASCII format) to
notify a status change or a power problem as it occurs. You can enable or disable
this option by using commands “510” and “509” respectively.

5.6 Input Parameters

The “INPUT PARAMETERS” provide UPS Input Voltage, Current, Volt

2

Amps, Pow er in Watts, P ower F actor , and Line F requency inf o rmation.

Voltage

The voltage measured at the input of the UPS (i.e., 120 VAC).

Current

The flow of current measured at the input of the UPS (i.e., 3.1 Amps).

Volt Amps

The apparent input power of the UPS calculated by multiplying input voltage

by the input current (i.e., 663 VA).

Power in Watts

The true input power of the UPS calculated in Watts (i.e., 600 Watts).

Power Factor

The ratio of true power (power actually consumed) to apparent power (simple

product of voltage and current) at the input of the UPS (i.e., 0.89).

Line Frequency

The frequency of the AC Line measured at the input of the UPS (i.e., 60 HZ).

5.7 Output Parameters

“OUTPUT PARAMETERS” provides UPS Output Voltage , Current, Volt

3

Amps, Power in Watts, Power F actor , and Line Frequency inf o rmation.
Note: UPS’s with dual output voltages offer the option of selecting and
viewing the V O L TAGE and CURRENT of each output individually .

Voltage

Output Voltage #1 displays the true RMS voltage for the 120 VAC side
(i.e., all 120 volt receptacles) and the voltage between L1 and N on the output
terminal block.

Output Voltage #2 displays the true RMS voltage for the 208 VAC or 240
VAC (i.e., all 208 VC or 240 VAC output receptacles) and the voltage between L1
and L2 on the output terminal block.

NOTE: The voltage between N and L2 can be calculated by subtracting
Output Voltage #1 from Output Voltage #2.

45

5. RS-232 TERMINAL COMMUNICATION

5.7 Output Parameters

Current

Output Current #1 displays the true RMS current on N. If there are no 120
V loads connected to N-L2, then this current represents the 120 V loads on N-L1
plus any equipment connected to the 120 V output receptacles.

Output Current #2 displays the true RMS current on L2. This includes the
current flowing in L2 of the output terminal block, plus the current flowing in all 208
V AC or 240 VA C receptacles.

NOTE: The total RMS current displa yed f or L1 and L2 may be different than
the sum of the individual currents flowing in each output receptacle and
terminal block. This is because of potentially nonlinear loads which have
currents that are not inphase with each other.

Volt Amps

The apparent output power of the UPS calculated by multiplying output
voltage by the output current. The total UPS output VA may not equal the sum VA
drawn from the connected equipment. This is due to different power factor rating
for each piece of equipment.

Power in Watts

The real output power of the UPS calculated in Watts. This will be equal to
the sum of the real output power for all equipment connected to the UPS.

Power Factor

The ratio of true power (power actually consumed) to apparent power (simple
product of voltage and current) at the output of the UPS.

5. RS-232 TERMINAL COMMUNICATION

5.8 Battery Parameters

“BA TTER Y P ARAMETERS” provides UPS Battery V oltage , Charger Current,
and Charger Status information.

4

Voltage

V oltage indicates the aver age DC voltage of UPS batteries. When the UPS is
running in “LINE PRESENT” mode and the batteries are charged, the voltage will be
approximately 27.6 VDC (equal to the charger’ s “FLOAT” charge). When the UPS is
running in “LINE FAILURE” mode, the battery voltage will slowly decrease until the
Battery Low V oltage Cutout is reached (appro ximately 21.0 VDC). Once utility power is
restored, after a prolonged power outage, the battery voltage will slowly climb until the
batteries are recharged.

NOTE: If e xternal batteries are connected, their voltage will be reflected as
well.

Battery Current

When the UPS is running in “LINE PRESENT” mode, the average DC charger
current is displayed (i.e ., 2.1 Amps). When the UPS is running in “INVERTER” mode
the battery charge current is zero (0).

Charger Status

When the UPS is in “LINE PRESENT” mode, the charger keeps the batteries
charged, indicated by “CHARGER STA TUS ON”. When the UPS is in “LINE FAILURE”
mode and running on the batteries, the charger immediately switches OFF, indicated
by the displa y “CHARGER STA TUS OFF”. Once utility po wer returns, or an alternative
power source (generator) is connected, the charger will switch ON and the DC current
will slowly rise after an initial 3 second “soft start” delay.

5.9 User Parameters

“USER PARAMETERS” allows you to set the information for automatic

5

test, output voltage shutdown, display unit identification, and to change
the security codes. Whenever one of the USER PARAMETER items is
accessed, you are prompted for a security code.

NOTE: The code (1111) is preset at the factory and can be changed by
entering the SET USER SECURITY CODE screen (menu item 58).

Unsolicited Alarm Messages

The CFR can transmit alarm messages (in ASCII format) to notify a status
change or a power problem. Once this feature is enabled, alarm messages are
transmitted automatically on the RS-232 port as soon as the status of the CFR changes.
Y ou can connect a terminal to the CFR to monitor its status and log all power prob lems.
Refer to menu items 56 and 509-511 for a detailed description.

Automatic Output Shutdown

The output of the CFR can be turned off by sending a command via the RS­232 port using a computer or terminal. Refer to menu items 501-508 a for detailed
description (menu items 501-506 are intended for scheduled shutdown even when the
AC line is present; 507 and 508 items can be used to switch the in v erter ON and OFF
to preserve the battery).

This command sets the
guaranteed down time after an output shutdown.

hh:mm:ss - hh is hours; mm is minutes; ss is seconds. Entering the
seconds is optional, (i.e. HH:MM format is also acceptable). The factory
default setting for this value is 00:00:05 which causes the CFR to remain in
shutdown for a minimum of 5 seconds. The CFR may restore output
immediately when this duration is expired, or may wait for the AC line to be
restored (depending on the setting of menu item 504). This feature requires
the USER SECURITY CODE for activation.

521

This menu displays all the current external modem values. Refer

to each individual menu item for a detailed description.

Enable Automatic Alarms:

Y= Yes, N= No, (Default value is “No”)

Setting “Enab le A utomatic Alarm” to “Yes” causes the modem to
dial out and report a problem whenever the specified power events (see
menu 522) happens. When enab ling this feature, ensure that the Unsolicited
alarm feature (menu 509) is disabled. Always enable this feature near the
end of the modem configuration because CFR will try to communicate to
the modem two minutes after activating this feature.

Enable Remote Access:

Y= Yes, N= No, (Default value is “No”)

Setting “Enab le Remote Access” to “ Yes” causes the CFR to set
the modem to answer remote calls on the first ring. Once a connection is
established, the remote host can access all CFR menus. The connection
exists until either the host drops the connection or the “Remote Hang Up
Time” expires (refer to menu 528). Enable this feature near the end of the
modem configuration because CFR would try to communicate to the
modem two minutes after activating this feature.

5.10 External Modem Parameters,

Set Alarm Actions:

522

CFR defines 20 different power events which are grouped in 8 alarm groups:

Alarm Group Power Events

1 UPS000 - power up
2 UPS001 - input out of tolerance

3 UPS005 - low battery warning
4 UPS006 - low battery shutdown

5 UPS007 - overload

6 UPS011 - service required
7 UPS013 - self-test started (Inv. on)

8 UPS017 - scheduled output shut down

0= None, 1= DIAL1, 2= DIAL2, (Default value is “11111111”)

Use this menu to specify what actions the CFR should take when various
power events take place. The three possible actions are:

— None: Ignore the event; do not take any action
— DIAL1: Call the DIAL1 phone number and report the event
— DIAL2: Call the DIAL2 phone number and report the event

UPS002 - input blackout
UPS003 - inverter on
UPS004 - line mode

UPS016 - battery OK

UPS008 - load OK
UPS009 - temperature high
UPS010 - temperature OK

UPS012 - UPS malfunction
UPS014 - self-test passed (line mode)

UPS015 - self-test failed
UPS018 - output shutdown

UPS019 - output restored

continued

Each digit in “11111111” represents the action f or one alarm group starting
from group 1 and up to group 8. The default action, “11111111,” means all alarm
groups are set to DIAL1.

Using this menu, you can specify an action for each alarm group. For
example, if we want the modem to call DIAL2 when the output shuts down due to
low battery and/or a fault and to send no alarm messages for self-test events, then
we should set alarm groups 4 and 6 to DIAL2 and alarm group 7 to NONE. This
setting is represented by “11121201”).

525

0-5 minutes
(default value is “0”; UPS003 and UPS004 are send immediately)

Transmission of the “UPS003 - inver ter on” message can be
delayed for 1 to 5 minutes to prevent short interruptions in the AC line
from being displayed. Setting this value to “0” causes UPS003 message
to be sent immediately. If the line retur ns and the CFR switches back to
the line mode before this delay time expires, then neither UPS003 or
“UPS004 - line mode” messages are sent for the event.

Set DIAL1 Phone Number:

dial command, 20 characters or less

(default value is “ATDT 234-5678”)

This command sets the modem command for DIAL1 action. The
CFR sends this string to the modem to initiate a DIAL1 action. The string
should start with “ATDT”, and is followed by the phone number where
DIAL1 events are being sent. Y ou can use all the dial command options
such as “,” and “W” (refer to your modem manual).

Set DIAL2 Phone Number:

dial command, 20 characters or less

(default v alue is “A TDT9,1-123-456-7890”)

This command sets the modem command for DIAL2 action. The
CFR sends this string to the modem to initiate a DIAL2 action. The string
should start with “A TDT” and is follo w ed by the phone number where DIAL2
events are being sent. Y ou can use all the dial command options such as
“,” and “W ” (refer to your modem manual).

Set Location ID:

526

user defined location ID, 20 characters or less

(default value is “CFR UPS in RM 123”)

This command sets the modem location ID . The modem location
ID is included as the first line of any event message that is sent by the
CFR. You may use this feature to define a location ID or a name for e very
CFR. This enables you to distinguish where and from which unit a message
is coming from.

This command is sent to the modem to initialize it. Refer to
section 4.2, “Configuring the modem to work with the CFR” to determine
the modem initialization string. The CFR sends this string followed by
the auto answer string to initialize the modem:

Set Remote Hang up Time:

0-100 minutes (default value is “2” minutes)

This command sets the time after which the CFR would hang-up
a nonactive remote call,
commands for this period, then the CFR forces the modem to drop the
connection. This prevents long delays in sending out alarm messages
when a remote host is hugging the line. Setting the hang up time to “0”

5.13 Event Descriptions (Alarms),

Several alarms can be triggered during the same event. If there is a loss of
AC line voltage, for example, the UPS may detect a glitch, low frequency and
blackout.

Low Battery W arning (LO_B A T_WARN) - The batter ies are near the end of
their useful charge. If AC line power is not restored within a short period of time, output
power will be lost. All systems should be shutdown immediately to prevent loss of
data.

Low Battery Shutdo wn (LO_BA T_SHTD WN) - To prevent an ov er-discharge
condition of the batteries, the unit has shutdown. Output power is terminated in this
condition.

Battery Voltage High (BAT_VOLT_HI) - The charging v oltage is higher than
the threshold setting for the batteries. This could be the result of a defective charger,
improper external battery connections, or defective batteries. Service the unit or batteries
to correct condition.

NOTE: This condition activates the SER VICE alarm, along with an audible
alarm which can be cleared by pressing the ALARM OFF or MUTE key.

Failed Self-Test (FAIL_SELF_TEST) - The unit could not maintain output
power while in the self-test mode. Check the batteries and circuit breakers.

NOTE: This condition activates the SERVICE alarm, along with an audible
alarm which can be cleared by pressing the ALARM OFF or MUTE key.

Battery Fault (BATT_FLT) - The battery charger is not able to supply the
proper amount of current or voltage to the batteries. This condition usually indicates
that the batteries are not connected or the BATTERY circuit break er is s witched OFF.

Glitch (GLITCH) - A glitch is a fast, low amplitude line disturbance where the
input voltage drops momentarily (less than 8 ms). * *

Spike (SPIKE) - A spike is a fast, high amplitude line disturbance where the
input voltage rises momentarily (less than 8 ms). * *

Sag (SAG) - A sag is a slow, lo w amplitude line disturbance where the input
voltage decreases for 8 - 40 ms. * *

Surge (SURGE) - A surge is a slo w , high amplitude line disturbance where the
input voltage increases for 8 - 40 ms. * *

Brownout (BR OWNOUT) - A brownout is a slow , lo w amplitude line disturbance
where the input voltage decreases for a long period of time (greater than 16 ms). * *

Slow Sur ge (SLO W_SURGE) - A brownout high (high ov ervoltage) is a slow,
high amplitude line disturbance where the input voltage increases for a long period of
time (greater than 16 ms). * *

continued

* * Indicates events that cause the UPS to operate in “LINE FAILURE” mode.

60

5. RS-232 TERMINAL COMMUNICATION

5.13 Event Descriptions (Alarms),

Blackout (BLACK OUT) - The blackout alarm is triggered when the input voltage

is lost for 12 ms, or when the RMS input voltage is less than 1/2 the nominal voltage
for 100 ms or longer. * *

Frequency High (FREQ_HI) - A frequency high alarm is triggered when there
is a power line problem where the input frequency increases beyond the preset limit.
* *

Frequency Low (FREQ_LO) - A frequency low alarm is triggered when there
is a power line problem where the input frequency decreases beyond the preset limit. * *

Output V oltage Low (V OL T_LO) - The output voltage low alarm indicates that
the output of the UPS is too heavily loaded, or there is a fault within the UPS. Reduce
the load connected to the UPS.

Output Volta ge High (VOL T_HI) - The output v oltage high alarm can be caused
by some equipment which draws power at irregular intervals. Disconnect all equipment
from the UPS and determine whether the fault will repeat. If it does, the unit may be
out of calibration, or there is an internal fault causing the overvoltage condition. Have
the unit serviced by an authorized Alpha Repair Depot.

Output Po wer Overload (PWR_OVLD) - The output pow er overload alarm
indicates a condition where the output of the UPS is too heavily loaded. If this is not
corrected, the unit may go into a shutdown condition to protect the UPS's internal
circuitry.

Output VA Overload (V A_O VLD) - The output V A overload alarm is triggered
when the RMS current exceeds the rating of the UPS. Reduce the load on the output
of the UPS to prevent overheating.

Output Over Voltage Fault (OVER_V_FLT) - The output overvoltage fault
alarm indicates a malfunction has been detected in the control circuit. The output
voltage has been shut off to protect the load from an overvoltage condition.

Output Short Ci rcuit (SHORT_CCT) - The output short circuit alarm indicates
a load was connected to the UPS that was shorted. This could be caused b y a
miswired A C power cord or equipment connected to the UPS that is in need of repair.

continued

NOTE: This condition activates the SER VICE alarm, along with an audible
alarm which can be cleared by pressing the MUTE ke y.

Internal Temperature High (AMB_TEMP_HI) - The internal temperature high
alarm indicates that the temperature of the UPS, measured by internal circuitry, w as
found to be too high. This could be caused by a sustained overload on the output of
the UPS, a blocked fan (if equipped), or operating the unit in an excessively high
ambient temperature. To prolong the life of the batteries and UPS components, determine
and correct the cause of the over-temperature condition.

* * Indicates events that cause the UPS to operate in “LINE FAILURE” mode.

61

5. RS-232 TERMINAL COMMUNICATION

5.13 Event Descriptions (Alarms),

Input Line Fail - Indicates that the UPS switched to backup power to protect

the equipment for one (or more) of the above conditions. * *

Normal Line Mode - Indicates that the UPS is drawing power from the AC line

and charging the batteries.

Test Mode - Indicates the UPS was put into a test mode condition either by
the TEST SCHEDULE routine or by pressing the TEST button on the Intelligent Interface
Device's panel. The unit will switch to backup power while in the test mode. * *

Float Charge Mode - This is the normal operating mode of the battery charger .
During LINE PRESENT operation, the batteries constantly receive a "Float" charge
voltage to ensure that backup power is available when required.

Service Codes (1-6) - These codes indicate a potential fault within the UPS .
Call Alpha Customer Support and report any displa yed Service Codes. Also refer to
the T roubleshooting section (6.7) of the manual.

Serv Code 1 - Phase Lock Loop Failure. The phase lock loop circuitry has
failed to lock onto the AC input LINE due to instability of the frequency. If the UPS is
operating from a generator , chec k the frequency and adjust it if necessary .

Serv Code 2 - Micro software reset. The internal “w atch dog” circuit has
detected a fault and reset the software. Contact Alpha to help determine the cause of
the fault.

Serv Code 3 - Micro hardware reset. A micro hardware reset is activated as
part of the power on condition. If this alarm occurs during normal operation, it may
indicate a malfunction in the hardware circuitry . Contact Alpha to help determine the
cause of the fault.

Serv Code 4 - Po wer board EEPROM fault. The EEPR OM on the power board
contains the unit configuration information. If this fault occurs, it signifies either the
configuration information has been corrupted, the EEPROM has malfunctioned, or
there is a loose connection inside the UPS.

Serv Code 5 - P ow er board hardware fault. The control circuitry on the power
board has detected a hardware fault condition which impedes correct operation of the
UPS.

Serv Code 6 - Neg DC supply rail fail. The negativ e v oltage pow er supply to
the microcontroller has malfunctioned.

6. MAINTENANCE

6.1 CFR Maintenance

The electronic components used in the UPS require no maintenance. If
the unit fails to perfo rm a specific function, ref er to the troubleshooting guide. The
guide lists typical symptoms, causes and solutions that apply to the UPS, starting
with the most obvious and working systematically through the unit.

By establishing a routine maintenance program and following the guidelines
contained in this manual, your Alpha CFR will continue to provide years of trouble­free service.

6.2 Battery Maintenance

The maintenance free batteries used in the UPS will be affected by many
variables including operating temperatures, number of discharges over the life of
the battery, charging characteristics, and low voltage cell cutoff. The Alpha CFR
complies with all factory recommendations for charging and discharging batteries
to ensure optimum performance and the longest possible battery life.

During normal operation, the UPS batteries will tend to increase in capacity
over the first three to twelve months of service. There can be as much as a 20%
increase in available backup power after the first ten to fifteen battery discharges.
Once the batteries reach this peak, they will slowly begin to lose capacity until,
eventually, they will be unable to pro vide the required bac kup pow e r.

Note: Battery
terminals vary in
size and shape.

6. MAINTENANCE

6.3 Battery Testing

To determine the maximum amount of battery run time available, run this
test at least once a year. The length of the test can vary from several minutes to
many hours and should not be done during critical applications. Since the test
discharges the batteries, backup power may not be readily available (for several
hours) in the event of a utility power failure.

1. Unplug the AC line cord from the wall receptacle. The front panel “LINE

FAILURE” LED will come ON. Make a note of the START time.

2. When the CFR reaches LOW BATTERY WARNING, record the time .

Subtract the START time to determine the actual safe run time. To cancel
the test, plug the AC line cord back into the wall receptacle.

3. T o determine the reserve time available , allo w the UPS to continue until it

reaches LOW BATTER Y SHUTDOW N. WARNING: This will cause the
load to go down . Make a note of the time. Subtract the LOW BATTERY
WARNING time to determine your available reserve time.

4. Switch the load OFF. Plug the AC line cord back into the wall receptacle.

The “L OW BATTERY WARNING” LED will remain ON until the batteries
are partially recharged. Switch the load ON, one de vice at a time . To
determine recharge time, subtract the time you resumed LINE PRESENT
operation from when the “LO W BATTERY W ARNING” LED goes OFF.

EMERGENCY SHUTDOWN

IMPORTANT

The CFR UPS contains more than one live circuit. During an emergency,
utility power may be disconnected at the service entrance or main electrical
panel to protect emergency personnel; however, power will still be present at
the UPS output.

To prevent the possibility of injury to service or emergency personnel, always
switch the UPS rear panel battery circuit breaker(s) OFF to deenergize the
circuit.

EMERGENCY SHUTDOWN PROCEDURE:

1. Switch the rear panel BATTERY circuit breaker OFF.

2. Unplug the AC power cord from the wall receptacle or the
back of the unit. If hardwired, switch the main panel AC
breaker to the UPS OFF.

On units equipped with an Emergency Power Off option: Press the wall­mounted EPO switch (RED) to automatically deactivate the CFR’s Battery
Circuit.
