Introduction

This section introduces you to the CFR 5000 and CFR 5000RM UPS’s:

• The CFR series many advantages (Section 1.1).

• An unpacking and inspection checklist (Section 1.2).

• An tour of the units, their connectors, switches and control panels (Section 1.3).

1 Introduction

1.1 The CFR Advantage

! Advanced Power Protection Technology

Alpha’s CFR Uninterruptible Power Supply (UPS) provides continuous and conditioned computer-grade AC power for computer systems, point of sale terminals, process controls, telecommunications, cable TV headend, broadband LAN, manufacturing control systems, hospital critical care and lab equipment.

Regulation

The unit maintains ±1% output regulation without using the batteries. Even with input voltage fluctuations as great as +10% or –20%, the output is constant regardless of the load’s size.

Isolation

The output is totally isolated from the input to protect the loads from spikes, surges and line noise. The ferro resonant transformer provides non-degradable spike and surge protection.

Extended Backup Capability

Alpha's EBP Series external battery packs extends backup time during power outages. Installing the battery pack is as simple as plugging it in.

! Self Test Function

The built-in self test checks all critical areas, including the batteries, to ensure optimum performance.

! Load and Overload Information

The display panel shows the loading and tells you when the unit is overloaded.

! Generator Ready

The unit has frequency sense and constant slew frequency synchronization circuits for trouble-free operation with most standby generators.

! Advanced Communications Capabilities

The RS–232 communications port is SNMP and modem compatible.

! Safety

Alpha designed the CFR to meet or exceed UL, CSA or VDE safety standards. This commitment to safety makes Alpha Technologies a leader in the power industry.

11 2 Installation

2.1 Pre–Installation Checklist

2.1.1 Site Preparation

Install the unit upright in a dry, well-ventilated, dust free environment. There must be at least 6 inches (152 mm) between the unit and the wall(s) for cooling and access to the front and rear panels. Do not place the unit next to air conditioning or heating thermostats.

Do not connect the unit to line conditioning equipment. This can cause improper operation of both the unit and the equipment.

Do not connect equipment that produces electrical noise such as motors, relay control circuits, copiers or laser printers to the same circuit as quieter or more sensitive devices. The unit cannot fully protect this type of equipment when noisy devices are connected. Electrically noisy equipment should be connected to a dedicated unit.

Place a warning label on the electrical panel so emergency personnel know a UPS is in the building. Label the service panel(s) to identify the circuit(s) supplying and being supplied by the unit.

2.1.2 Grounding & Utility Line

All wiring should be done only by qualified personnel and comply with the local electrical code.

The unit’s input and output voltage is factory configured to your specifications. If you need to change either one or both, see Section 5.5, “Configuring the Input/Output Voltage.”

If required, install a hardwired ground. Since many older facilities have improper grounding, a qualified electrician should inspect both the wiring and the grounding before installation.

Measure the line voltage at the main electrical panel. Compare that reading with the input rating of the unit as listed on the nameplate label on the back panel:

• 240 VAC units: the voltage must be between 216 VAC and 252 VAC.

• 230 VAC units: the voltage must be between 207 VAC and 242 VAC.

• 208 VAC units: the voltage must be between 188 VAC and 216 VAC.

• 120 VAC units: the voltage must be between 110 VAC and 125 VAC.

Also see Section 2.8, “Transformer Output Load Sharing.”

Alpha Technologies

2 Installation 12

2.1 Pre–Installation Checklist (Continued)

The unit should be wired to dedicated circuit equipped with a properly sized circuit breaker. The breaker’s size is the unit’s maximum input current (as given in the specifications) plus 25%.

For example if the unit draws 32.0 Amps of current at 208 VAC, adding 25% the input current becomes 40.0 Amps. A 40 Amp circuit breaker would be OK. Always follow the local electrical code when installing or sizing circuit breakers.

2.1.3 Standby Generator

The unit has frequency sense circuits for operation with most standby generators. Use a generator equipped with electronic speed and voltage controls since the unstable frequencies created by a mechanical governor can make the unit run continuously in line failure mode, draining the batteries.

Before installation see that the generator’s output voltage meets the unit’s input voltage requirements as shown on both nameplates. A 240 VAC unit must be attached to a 240 VAC generator.

Transformer Output Current Ratings

Since loads are shared between windings, you can exceed a winding’s output without exceeding the unit’s maximum current output. There are two ways to calculate the current drawn by the loads; measuring or displaying the output current.

2.8.2.1: Measuring the Output Current

This uses a clip-on current probe (Figure 2.12 for 240 VAC, Figure 2.13 for 208 VAC and Figure 2.14 for 230 VAC).

For 120/208/240 VAC units the total current drawn from Winding 1 is the sum of the currents A, B and C where:

• A is the total current drawn by all of the 120V loads connected to the receptacle.

• B is the total current drawn by all of the 240V loads connected to the receptacle.

• C is the total current drawn from the L1 side of the terminal block.

The total of these currents must not exceed the rated output current for the L1 winding.

For the L2 winding of the transformer, measure the currents at points B and D where:

• B is the total current drawn by all of the 240V loads connected to the receptacle.

• D is the total current drawn from the L2 side of the terminal block.

The total of these currents must not exceed the rated output current for the L2 winding.

2.8.2.2: Displaying the Output Current

TIP: When using the display panels, you must calculate L1’s current as described

below.

Using the SID Display Panel:

230 VAC

The current is displayed via RS–232 as Output Current 1 and Output Current 2 (Section

4.4.3).

Use the menu to display Output Current 1 and Output Current 2.

The current in Winding 1 (Output Current L1) is the sum of Output Currents 1 and 2.

The current in Winding 2 is Output Current 2.

The Overload LED will flash if the total current in either winding exceeds its maximum rating or if the total output in VA or Watts exceeds the unit’s maximum output.

Using the IID Display Panel:

Use the menu to display Output Current 1 and Output Current 2.

The current in Winding 1 (Output Current L1) is the sum of Output Currents 1 and 2.

The current in Winding 2 is Output Current 2.

This section shows you how to operate the CFR 5000 and CFR 5000RM UPS’s:

• How to turn the unit on and off (Sections 3.1, 3.2).

• How to start the unit’s self test (Section 3.3).

• How to troubleshoot the unit with the SID (Section 3.4).

• How to use the Standard Interface Device (SID) (Section 3.5).

3 Operation

3.1 Turning On the Unit

WARNINGS:

1) This unit runs warm to the touch. During the first few weeks of operation, a brand new

unit may give off an odor caused by the burning of the transformer’s lacquer finishing. This is normal and is not toxic.

2) The unit generates electromagnetic radiation. Keep all sensitive magnetic media such as floppy disks, recording tape, key cards, bank and credit cards away from it.

Procedure:

Switch off:

• All loads connected to the unit.

• The input and battery circuit breakers.

Switch on:

• The utility panel’s main breaker.

• The breaker supplying power to the unit.

Switch on the input circuit breaker.

The display panel’s Line Present LED turns on to show the unit is running on line power.

TIP: There is a delay of 5 to 15 seconds before the unit energizes. If it has an SID, the Test LED flashes.

If the unit does not turn on, perform troubleshooting (Sections 3.4, 5.2). Do not perform a cold start.

Switch on the battery circuit breaker.

Do a self test (Section 3.3, “Testing the

Unit”).

One at a time, turn on the loads.

Alpha Technologies

33 3 Operation

3.5 Controlling the Unit With the Standard Interface Device (SID) (Continued)

Low Battery Shutdown

This red LED turns on when the battery voltage is 12% below nominal. The unit automatically shuts itself down and no longer provides power to the loads to prevent overdischarge damage to the batteries.

Test

This yellow LED shows the unit is in self test mode (Section 3.3). If it fails the test, the Service LED is on and the unit defaults to Line Present operation. You should do troubleshooting as shown in Sections 3.4 or 5.2.

TIP: At start-up, this LED flashes for about 5 to 15 seconds.

Line Synchronization

If both the:

• Line Present

• Line Failure

LEDs are on, the unit is synchronizing its output with the input before starting Line Present operation. This takes about 15 seconds.

4.7 Installing and Using the External Modem

Uses of the External Modem

Where a network is not available, you can connect an external modem to the CFR’s RS–232 port.

The modem lets you:

• Program the CFR to send an alarm message to a remote host via the telephone line when a power event takes place.

• Dial up the CFR for remote monitoring or control. Once connected, all RS–232 menus are accessible.

Equipment and Settings

Equipment:

• An external modem (US Robotics Sportster (1200, 9600, 19.2K or 28.8K baud) or other “Hayes Compatible” modem).

• A standard null modem cable, DB–9 male to DB–25 male.

• Phone line access.

• One-time access to the CFR via a computer link.

Settings:

• RS–232 Speed: 1200 Baud between CFR and modem.

• RS–232 Signals: Rx, Tx and Gnd.

• Handshaking: None, neither hardware (RTS/CTS) nor software (XON/XOFF) are

used.

• Modem Speed: Same as the modem’s.

Alpha Technologies

51 4 Communication

4.7 Installing and Using the External Modem (Continued)

Step 1: Enable the CFR’s Modem Feature

The CFR is shipped with the modem feature disabled. To enable it:

Connect a computer to the CFR’s RS–232 port (Sections 2.6, 4.1).

Go to Menu Item #52 (Figure 4.19).

(For explanations of each item see “Modem Setup and Control: Sub Menu #52” in this section.)

External Modem Setup

520 Enable Automatic Alarms (No) 521 Enable Remote Access (No) 522 Set Alarm Actions (11111111) 523 Set Inverter Alarm Delay (0) 524 Set Dial 1 Phone Number (ATDT 234-5678) 525 Set Dial 2 Phone Number (ATDT 234-5678) 526 Set Location ID (CFR UPS in Rm 123) 527 Set Custom init cmd (ATDT X4Q0V1&H0&R1&I0&B1) 528 Set Remote Hang up Time (2) Last Modem Response (N: )

Figure 4.19

External Modem Setup Screen (Showing Default Values)

To enable the Automatic Alarm notification, change the following:

i Make sure “Unsolicited Alarms” (Item #509) is disabled (blank instead of “active”).

ii Set the monitoring station’s phone number in Items # 524 “Dial 1” or #525 “Dial 2”

iii If you are not using a US Robotics Sportster, set “Custom Init cmd” (Item #527) to

the values your modem uses (Step 2: Connect and Configure the Modem, #3).

iv If you have more than one unit, set the “Location ID” (Item #526) to a unique, de-

scriptive string (e.g. Rm 222).

Set “Enable Automatic Alarms” (Item # 520) to YES.

If you want remote dial-in access to the RS–232 menus, set “Enable Remote Ac-

cess” (Item #521) to YES.

Alpha Technologies

4 Communication

4.7 Installing and Using the External Modem (Continued)

Step 2: Connect and Configure the Modem

Use a shielded, null-modem serial cable, DB–25 male to DB–9 male, to connect the modem to the CFR.

The most common ways to connect the cable are:

• A null-modem cable with DB–25 male to DB–-9 male ends (Figure 4.20).

• A null-modem cable with DB–25 male to DB–25 male ends and a 9–25 adapter.

• A standard straight-through cable with DB–9 male to DB–25 female and a null-

modem adapter.

4.7 Installing and Using the External Modem (Continued)

The initialization string (Item #527) is a set of commands the CFR sends to the

modem to initialize it. For a US Robotics modem, the string is:

• ATX4Q0V1&H0&R1&I0&B1

Where:

• 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 time).

• &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. The last four are supported by US Robotics and some other manufacturers.

TIP: Do not include the auto answer command in the initalization string. The CFR sends an AT command to control the auto answer mode (either “ATS0=1” or “ATS0=0”).

For modems that do not support the extended Hayes commands, you should create an equivalent command. In most cases the simplified string:

• ATQ0V1

works well.

Alpha Technologies

4.7 Installing and Using the External Modem (Continued)

Step 3: Initalize the Modem

To initalize the modem start a CFR self test (Section 3.3).

The CFR must initialize the modem. If a remote host calls before initialization, the CFR/ modem combination will not answer the call.

TIP: If the modem is set for auto answer and a call is answered before the CFR initalizes it, the modem uses its own baud rate which may not be the 1200 baud used by the CFR. In this case the CFR cannot talk to the modem.

The modem must be set for No Answer. When the CFR initalizes the modem, it automatically sets the RS–232 rate to 1200 baud.

The CFR automatically sends out the initialization string (Item #527):

• One minute after CFR power up and then every hour after.

• At the start of a self test.

• Before sending out the first automatic alarm.

• Every two minutes after a failed modem command (dial, hang or initialize).

• After starting one of the modem options.

This guarantees the modem is initialized before sending out the first automatic alarm.

If initalization fails, the CFR assumes the modem is on line, sends an escape sequence, resets the modem and then resends the initalization string. This will not work if the modem is using a different baud rate than the CFR’s. If this fails, the CFR sends the initialization sequence every two minutes until initalization is successful.

Step 4: Accessing the RS–232 Menus (If Used)

Enabling the remote access feature (Item #521) allows you to call the CFR to have access to all RS–232 menus. The auto answer command (ATSO=1) is sent to the modem during initalization.

If a call is in progress and no RS–232 commands are received for longer than the remote hang up time (Item #528) the CFR tells the modem to disconnect from the host. This stops a faulty host from tieing up the phone line and preventing other calls from being received or alarms from being sent out.

How the CFR Sends Alarms

To send an alarm, the CFR sends the dial command to the modem and waits up to 60 seconds for a “connect.” If this fails, it will try the same dial command two minutes later if the modem responds back to the CFR with a “No Carrier,” “No Dial Tone” or “Busy” messages.

If the modem does not respond (it is disconnected, not powered or is inoperable), the CFR tries to initalize the modem. It then sends a dial command every two minutes until it is successful. A successful command is when the modem replies with a “connect” message in less than 60 seconds.

The CFR stores alarm messages in a buffer that holds up to 7 messages. When the modem is operating, it sends the alarms out in the order they occurred. If the buffer is full, the oldest message is discarded and the newest added.

After sending the alarms, the CFR sends a escape command (+++) followed by the hang command (ATH) to the modem to end the session.

Modem Setup and Control: Sub Menu #52

Sub menu #52 (Figures 4.19 and 4.22) allows you to set up the modem, set the Dial 1 and 2 phone numbers and give the CFR an identity.

For most functions you will be asked for a password. The factory set password is 1111. If you change it, make sure a written copy is kept in a safe and accessible place.

Section 5

Maintenance

This section describes how to maintain the CFR 5000 and CFR 5000RM UPS’s:

• How to measure the battery backup time (Section 5.1).

• How to troubleshoot the unit (Section 5.2).

• How to return the unit to Alpha for repair (Section 5.3).

• How to replace the CFR 5000’s internal batteries (Section 5.4).

• How to change the unit’s input and output voltages (Section 5.5).

• Typical battery run times (Section 5.6).

• Specifications (Section 5.7).

5 Maintenance

5.1 Testing the Battery Backup Time

This test measures how long the batteries can provide backup power by having them power the loads until they are discharged.

Tips:

• This test should be done once a year when the batteries are new. When the batteries are

three years old or older, it should be done once every six months.

• This test should be done when new loads are connected to the unit.

• The unit should have been in Line Present mode for 24 hours before starting this test so

the batteries are fully charged.

• Do a self test first (Section 3.3). If it passes, do this test. If it doesn’t, find out why before proceeding.

• For reference, compare your measured time to the times listed in Section 5.6, “Battery Run Times.” Because of various factors, your time may not match the times listed.

Procedure:

Switch off the Input circuit breaker.

The display panel’s Line Failure LED turns on. The unit is operating on backup battery power.

Record this start time.

The Low Battery Warning LED turns on.

Record this time.

The run time is the time between 1 and

Turn on the Input circuit breaker.

The unit runs on line power and the batteries start charging

Battery Backup Time Test Finished

Alpha Technologies

5 Maintenance

5.2 Troubleshooting

Most problems involve:

• Are the input, battery and output circuit breakers switched on?

• Is the input voltage correct?

• Are the batteries expired?

If the unit fails to perform a specific function, Figure 5.1 lists typical symptoms, causes and solutions, starting with the most obvious and working systematically. If you cannot resolve a problem, contact Alpha’s customer service department. The unit’s electronics require no maintenance.

Battery Lifetime

The maintenance-free batteries can be affected by: operating temperature; number of discharges during the battery’s life; charging characteristics and low voltage cutoffs. The unit complies with the battery manufacturer’s specifications for optimum performance and the longest possible battery life.

In normal operation, the batteries may increase in capacity during the first three to twelve months. After the first 10 to 15 discharges, the available backup power may increase by up to 20%. Once at this peak they slowly loose capacity and eventually cannot provide backup power.
