1.0 INTRODUCTION

The Liebert AC8 is ideal for coordinated control of systems with redundant equipment, such as multiple environmental units or pumps. When the AC8 controller detects an alarm in an operating device, the AC8 enables a standby device and controls the device in alarm as configured, either leaving that device operating or disabling it.

The AC8 controller can also balance usage of devices by rotating units through Operating and Standby modes according to a user-defined schedule. This helps keep redundant equipment operating efficiently and only when needed. The AC8 can perform routine testing of standby devices and alert personnel if a standby device fails an operating test and requires attention.

The staging feature permits standby devices to be turned on or off when a sensor detects specified levels. For example, the AC8 might be configured to turn on a fan when the temperature reaches 75°F, then turn on a second fan at 80°F. When the temperature falls below 80°F, the second fan is turned off; when it drops below 75°F, the first fan is turned off.

Another capability of the AC8 is monitoring the status of connected devices and keeping personnel apprised through local alarming. The AC8 employs local alarming and remote paging services to keep personnel on-site and at remote locations apprised of the status of equipment.

The AC8 controller can interface with anything that closes an electrical contact. To improve process efficiency and troubleshooting, the controller tracks data in three types of logs: alarm, event and trend. The AC8 has a local LCD interface and a remote dial-up interface.

When an alarm condition arises, the AC8 displays alarm information, sounds an audible alarm, changes the state of the common alarm relay and turns connected devices on or off according to user configuration. If configured, the controller also sends pager notifications. See 1.6 - Typical Configu- ration for a more detailed example.

Introduction

1.1 Methods of Viewing and Configuring the AC8

The AC8 features access through two interfaces that allow users to configure the unit, silence alarms, back up logs, and perform many other functions to keep a large or small operation running smoothly and safely.

• LCD—liquid crystal display on the front of the panel

• Service Terminal Interface—accessible via computer connected directly through an RS232 port or remotely through the AC8’s onboard modem

These interfaces permit easy access and configuration of the AC8, allowing users to view data, silence alarms and have full access to information stored in the controller, including logs of alarms and events.

One more interface—Liebert’s SiteScan Web enterprise monitoring system—is primarily for monitoring, though SiteScan also provides some configuration functions.

1.2 Data Logs

The three types of data logs—alarm history, event history and trend data of analog sensor readings— can be viewed on the LCD on the front of the AC8 and downloaded through onboard communications ports.

1.3 Transformer Module

A Transformer Module converts 115VAC or 230VAC to 24VAC.

1.4 Available Alarms

The alarms available with the AC8 are:

• Discrete input alarm (for each digital input)

•High setpoint

• Low setpoint

• Loss of power

• Low battery

• Check battery

• Battery unplugged

• Internal modem fault

• No standby available

• Standby device failed

• No restart available

• Emergency power alarm

1.5 Outside Enclosure Overview

BAR CODE

SENS

The AC8’s controller board comes in an enclosure that is 2-3/4" deep and has a built-in liquid crystal display (LCD) and a key lock, as shown in Figure 1. The enclosure is made of metal to accommodate secure conduit fittings and protect components against environmental debris.

Figure 1 AC8 enclosure—external features

The enclosure has knockouts and access slots on top and bottom for cables and wires.

Introduction

LCD for configuration and operation

Key lock

The enclosure houses the controller board and Transformer Module, as shown in Figure 2.

The enclosure must be secured to a wall, either flush-mounted or recessed in the wall, as described in

2.0 - Installation. Knockouts and access slots on the top and bottom allow easy connection of wires and cables (see 3.0 - Wiring and Connections) with either mounting type.

1.6 Typical Configuration

BAR CODE

Figure 3 shows an example of external devices connected to the AC8’s controller board. Up to eight devices may be connected to the eight digital inputs and eight digital outputs. There may be up to four analog sensors connected to the analog inputs, and up to two devices connected to the control relay outputs. The EPOP connection allows for one device, possibly a UPS or generator input actuated during a power failure.

Remote access is available via SiteScan Web and through the modem, which enables pager notifications and use of the Service Terminal Interface. A computer may be connected to the RS232 port, providing access to the features of the Service Terminal Interface.

Jumper to disable the audible horn (factory default is enabled). N/A

The two common alarm connections are used to connect to a secondary warning device such as a horn, light or Building Management System (BMS). When an alarm is present, the contacts close and the external warning device is activated/notified. The common alarm contacts may be configured to be reset with the Silence button/command.

Each output has an LED to indicate its status: ON/OFF (energized/deenergized).

Each of the two output connections is a two-state point: ON/OFF (energized/de-energized). Digital and analog inputs may be mapped to either or both relays to trigger change in state. An example of a control relay output point is a humidity lock-out.

Placing the switch in the ON position will turn ON, or energize, all eight outputs simultaneously. This switch removes all automatic output control from the AC8.

2.0 INSTALLATION

This section provides instructions for installing, mounting and connecting power to the AC8.

2.1 Installation Considerations

The AC8 must be installed indoors and may be mounted on the surface of a wall or flush-mounted, depending on the user’s application, the location of equipment and sensors to be monitored and the type of wall the unit will be mounted on.

The AC8 should be mounted where it can be easily accessed. On-site personnel would access the unit through the LCD on its front cover, service terminal connected to the RS232 port or through SiteScan. For off-site monitoring, the AC8 should be placed near communications means such as a telephone line connection that would permit remote access.

In addition to the communications connections, the site also must have electrical service and must permit connecting the unit’s eight digital inputs, eight digital outputs and four analog inputs.

The wall material must be capable of supporting the weight of the AC8: see 8.0 - Specifications.

NOTE

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.

Installation

2.1.1 Unpacking and Preliminary Inspection

• Before unpacking the AC8, inspect the shipping carton for damage or signs of mishandling, such as gashes or holes in the carton or severely flattened corners.

• Open the shipping crates carefully. Use care to avoid puncturing the container with sharp objects that might damage the contents.

• Inspect the AC8 and all included components for damage.

• If any damage from shipping or mishandling is observed, immediately file a damage claim with the shipping agency and forward a copy to:

Liebert Corporation 1050 Dearborn Drive P.O. Box 29186 Columbus, OH 43229

Packing Contents

Table 3 Packing manifest

Standard Components

• AC8 controller board in enclosure

• User Manual

• Keys (2) to panel door lock

• Backup Battery - installed in unit (not connected or charged)

• RS232 Configuration Cable

2.2 Surface-Mounting the AC8

NOTE

Removing the conduit knockouts before mounting the AC8 on the wall will ease installation and prevent strain on the mounting hardware and wall. It is imperative to remove the knockouts if the unit is to be flush-mounted.

After determining where to place the unit, check to ensure that you have all the hardware required to install the panel on the surface of a wall. Obtain the needed tools and material.

Required tools

• Electric drill (if surface is too hard to drive screws without pilot holes)

• Screwdriver

• Marker to denote layout of holes

• Four screws, each #10

2.2.1 Mounting the Panel

CAUTION

Check building plans and other relevant documents to determine whether mounting the AC8 at the selected location might cause cutting or otherwise damaging electrical or communication wiring or pipes.

1. Mark the wall for mounting holes, using the back of the unit as a template (see Figure 5).

2. Drill holes, if required, to install the four #10 screws that will secure the AC8 to the wall. Clean up the debris.

3. If the wall material is not strong enough to hold the screws securely, use wall anchors.

4. Install the top two screws—the screw heads must be small enough to slip through the larger, bottom portion of the pear-shaped mounting slot in the AC8 (see inset in Figure 5). The screws must also be large enough to extend over the edges of the top of the mounting slot.

5. Hang the AC8 on the screws, letting the panel slip down until the screws are in the smaller, upper portion of the slot.

6. Tighten the screws until they are snug.

7. Insert the remaining two screws in the bottom holes on the back of the panel and tighten.

2.3 Flush-Mounting the AC8

NOTE

The rectangular access doors on the top and bottom of the AC8 must be reversed so they slide the opposite direction. Leaving the doors as shipped from the factory prevents them from being opened when the panel is flush mounted in a wall.

The AC8 may be flush-mounted according to company practices—either with screws through the sides of the panel into wall supports or with hanging hardware that attaches to the back of the panel. After determining how and where to place the unit, check to ensure that you have all the hardware required to install the panel in the wall. Obtain the needed tools.

Required tools

•Saw

• Electric drill

• Screwdriver

• Marker to denote layout of the hole to accommodate the AC8

• Mounting hardware

2.3.1 Mounting the Panel

Installation

CAUTION

Check building plans and other relevant documents to determine whether mounting the AC8 at the selected location might cause cutting or otherwise damaging electrical or communication wiring or pipes.

1. Mark the wall for the cutout to accommodate the panel, using the back of the unit as a template.

2. Drill a pilot hole for the saw blade, if required.

3. Use the saw to cut out the marked section of the wall (if not new construction).

4. Rest the AC8 in the wall and mark where mounting screws will be inserted into the wall studs or other support member.

5. Remove the panel and drill the holes for the mounting screws or wall anchors. Clean up the debris.

6. Reverse the slide direction of the rectangular access doors on the top and bottom of the AC8. Leaving the doors as shipped from the factory prevents them from being opened when the panel is flush mounted in a wall.

7. Attach any field-supplied mounting hardware.

8. Reinsert the assembly into the wall.

9. Insert and tighten the screws or wall anchors.

2.4 Connect Power to the AC8

The AC8 must be supplied with 115VAC or 230VAC; the power supplied must match the rating of the unit’s Transformer Module. For information, consult your local dealer, Liebert representative or the Liebert Worldwide Support Group.

3.2 Connecting Digital Inputs and Digital Outputs

The digital inputs, digital outputs and control relay outputs are found on the right side of the AC8’s printed wiring assembly board. Each set has two terminal blocks—one green, the other black:

• Digital inputs: two terminal blocks, with four inputs per block (8 inputs total)

• Digital outputs: two terminal blocks, with four outputs per block (8 outputs total)

• Control relay outputs: two terminal blocks, with one output per block (2 outputs total)

Each input is tied to an output with the same number:

• Input 1 is tied to Output 1 (default name: Device_1)

• Input 2 is tied to Output 2 (default name: Device_2)

• Input 3 is tied to Output 3 (default name: Device_3)

. . .

• Input 8 is tied to Output 8 (default name: Device_8)

Up to eight devices may be connected to the AC8. Each device must be connected to an input and an output with the same number.

To determine the proper wire size, see Table 4 - Wiring specifications.

NOTE

Each terminal block is a removable, two-part assembly to permit easier connection of more than one input at a time. If making multiple connections, grasp the upper portion of a block and pull firmly to the right until the assembly pulls apart.

After making the connections, push the removed piece back into the portion attached to the printed wiring assembly until the terminal block pieces lock together.

Wiring and Connections

Connecting Liebert Environmental Units

For Liebert environmental units, follow these steps (be sure to connect the same device to inputs and outputs with the same number—one device to Input 1 and Output 1, another to Input 2 and Output 2, and so on):

• Connect a digital input from the AC8 to the Common Alarm Relay of the environmental unit: terminals 75/76 or TB1-6, TB1-7.

• Connect a digital output (numbered the same as the input) from the AC8 to the Remote Shutdown (Power Control) of the environmental unit: terminal 37/38 or TB1-4, TB1-5.

3.2.1 Connecting Digital Inputs

To connect a digital input:

1. Turn OFF electrical power to the AC8.

2. If necessary, remove a conduit knockout to permit wire entry into the AC8 enclosure.

3. Bring the wire(s) into the AC8 enclosure through a conduit knockout or access slot.

4. Loosen the appropriate screw and slip the stripped end of the wire into the terminal block.

5. Tighten the screw until it holds the wire snugly.

NOTE

Connect digital inputs to nonpowered (dry) contacts only.

3.3.2 Connecting the Analog Ground

The AC8 features an analog ground connection for four-wire sensors that have an external power source. Such a four-wire sensor requires a reference to ground because they get power from an external power source.

A two-wire transducer, which does not have an external power source, does not need to be connected to the analog ground.

The analog ground connector has two terminals, each of which can accommodate two wires. This is adequate to connect four sensors that require a reference to ground because they get power from an external power source.

Connect the analog ground to an external four-wire sensor, as shown in the illustration at right.

7.3.4 Set Up Alarmable Inputs in Latched or Unlatched Mode

Alarmable input points may be set up in Latched mode (Y), which requires the user to clear the AC8 alarms after an alarm has occurred, or Unlatched mode (N), in which alarms will automatically clear after a return-to-normal state. The default setting for alarmable inputs is L(Latched).

Any input defined as an event is automatically Unlatched.

A digital input defined as Latched does not reset automatically after an alarm. It will remain in the triggered position even after the moni- tored device returns to normal. After an alarm, the user must manually reset Latched inputs, as described in 7.13.1 - Clear Active Alarms. This also means that any digital outputs linked to a Latched digital input will remain triggered until the input is manually reset.

A digital input defined as Unlatched will automatically track the status of the monitored device. No action by the user is required.

• From the Setup Inputs Menu, choose Latched, as shown above

right, and press Enter ↵.

• To change this feature, use the arrows

Latched) or N (No - Unlatched), then press Enter ↵.

NOTE: Only alarmable input points may be set up as Latched. Once an input is defined as an event, the Latched entry displays N/A. If you attempt to set up an event as Latched, the message shown at right appears. Press the ESC key to return to the previous screen to continue configuring the digital input.

The only way to reset latched alarms is by clearing active alarms. This step is required to return latched points to their normal state. For details, see 7.13.1 - Clear Active Alarms.

7.3.5 Set Up Delay Time

Each input may be set up with a specified time delay between the occurrence of an alarm or event—a monitored device changes state— and any response by the AC8. This feature can prevent needless responses to transient conditions.

This delay is the amount of time that must elapse before the AC8 acknowledges the change of state in the monitored device and takes any further action, such as dialing configured pagers. The default time delay is 1 second (displayed as 00 MIN : 01 SEC).

The time delay applies only when a monitored device changes from its normal state—for example, the AC8 detects a closed contact that is defined as Normally Open.

When the monitored device returns to its normal state, the AC8 acknowledges the change of state immediately.

• From the Setup Inputs Menu, choose Delay, as shown at right,

and press Enter ↵.

• To change the time delay in minutes and seconds (in the range of 00:00 to 99:59):

7.4 Setup System - Setup Common Alarm

The audible alarm sounds after the AC8 detects an alarm condition in any input that has been defined as alarmable, including digital and analog sensor inputs. Once the alarm is silenced, there are two options:

• By default, the common alarm remains energized until the input alarm is cleared.

• You may change this setting to de-energize the common alarm automatically once the alarm is silenced.

You might want to reset the common alarm with silence if an external alarm—for example, a horn—is connected to the common alarm output contacts.

You might not want to reset the common alarm contacts (let contacts reflect/track alarms) and simply silence the audible horn.

7.6 Setup System - Setup Zones

The AC8 has four zones that may be used to define different areas—rooms or sections of a room. If set up with four zones, the AC8 effectively performs as four separate units, controlling each zone separately, for example, using a different rotation sequence for devices in each zone.

System and Control Options

A single zone may have one to eight outputs associated with it. The minimum number of outputs per zone is one, and the maximum for all zones combined is eight.

By default, the AC8 is configured to have one zone with four outputs: Zone 1 has four associated outputs and Zones 2-4 have none.

To set up zones:

• From the Main Menu, use the arrows

Control, then press Enter ↵ (see 7.1 - Login for help).

• Enter your password at the Login screen.

• From the System and Control Menu, use the arrows

By default, the AC8 checks the battery and sounds an alarm when the power fails, the battery runs low or the battery needs to be checked. The battery’s main purpose is to provide enough power to the modem to notify pagers of a power loss.

NOTE

The battery will continue to power and provide full operation of the AC8 with the exception of powering the analog inputs (sensors). The battery will provide backup for a minimum of 10 minutes.

Using the following procedure to disconnect the battery will disable battery alarm features only. The battery itself will continue to provide backup. If battery backup is not desired, the battery must be unplugged from the circuit board. This can be done by removing the battery leads from the jumpers (see 2.4.2 - Connecting the Battery Pack).

7.10.1 Turn Automatic Sequencing On or Off

Use automatic sequencing to set up a schedule for rotation of redundant devices. For example, three devices might be in operating mode while a fourth device is in standby mode. Every two days, the AC8 returns the standby device to operating mode and places one of the operating devices on standby.

When zones are used, the AC8 manages the rotation sequence for each zone separately, so each zone might have one device in operating mode and one in standby mode.

NOTE

Auto sequencing will not function in a zone with any devices defined as Not Used. All outputs in the zone must be defined as Operating or Standby (see 7.7 - Setup System - Setup Outputs).

Auto sequencing is OFF (deactivated) by default. When auto sequencing is activated (ON or 12h, for a 12-hour interval), the AC8 cycles devices at the specified interval and time of day as follows:

• An output device in Standby mode is returned to Operating mode.

• An output device that is Operating is put in Standby mode.

When more than one device is in Standby mode or turned On, the AC8 performs the operations in a sequence that rotates the order. For example, in a sequence set up to occur every two days:

• Monday: Device 1 is placed on Standby, and Devices 2, 3 and 4 operate.

• Wednesday: Device 2 is placed on Standby, and Devices 1, 3 and 4 operate.

• Friday: Device 3 is placed on Standby, and Devices 1, 2 and 4 operate.

• Sunday: Device 4 is placed on Standby, and Devices 1, 2 and 3 operate.

System and Control Options

NOTE

The AC8 will not cycle outputs that have been manually forced On or Off through the Override Output Menu or the hardware switch (see 7.12 - Override Output).

7.10.2 Turn Standby Testing On or Off

Standby testing permits scheduling an automatic operational check of devices in Standby mode.

When this feature is activated (ON), the AC8 tests all devices in Standby mode by putting each device in operating mode for a designated time. If an operating unit is designated as disabled on alarm, the unit is turned off during standby testing, then turned on when the test ends.

You may specify the time of day the testing begins, the duration of the test and the interval between tests. Standby testing is OFF (deactivated) by default.

7.10.3 Specify Failed Standby Response

The AC8’s Failed Standby feature determines what happens when an operating device fails and a standby device then becomes an operating unit. A subsequent alarm in the newly operating unit (previously the standby device) results in either restarting the previously operating device that was alarmed or not. This feature specifies whether each device remains in its current state or returns to its previous state of operation.

When this feature is activated (Y), each device returns to its previous state, as Table 29 shows. The newly enabled Standby device is disabled; the previously operating device returns to Operating mode.

The default setting is N (deactivated), meaning that each device remains in its current state: the Standby device remains enabled and the previously operating unit remains disabled.

Table 29 Failed Standby response

7.10.4 Specify Hold Delay Time

After an output changes state, the hold delay timer directs the AC8 to ignore all inputs in the same zone for the specified time.

This delay is the amount of time that must elapse before the AC8 acknowledges a change of state in any input. The default is 10 minutes (displayed as 10 MIN : 00 SEC).

The time delay applies only when a monitored output device changes from its normal state—for example, the AC8 detects a closed contact that is defined as Normally Open.

System and Control Options

When the output device returns to its normal state, the AC8 acknowledges any input change of state immediately.

The hold delay timer also takes effect when the AC8 is powered up. All alarms are ignored until the hold delay time expires.

To change the Hold Delay Time settings:

• From the Setup Operation Menu, choose Hold Delay, as shown at

right, and press Enter ↵.

• To change the time delay in minutes and seconds (in the range of 00:00 to 99:59):

• For minutes (MIN), press and hold one of the arrow keys scroll through the numbers 00-99.

• Press Enter ↵ to advance to seconds (SEC).

• For seconds (SEC), press and hold one of the arrow keys scroll through the numbers 00-59.

• When finished, press Enter ↵ again.

7.10.5 Specify Restart Time

The restart delay timer directs the AC8 to wait a specified time before changing the state of an output. This feature can prevent needless responses to transient conditions.

If two or more outputs change state simultaneously, the AC8 begins a new countdown between each output change of state.

The default is 6 seconds (displayed as 00 MIN : 06 SEC).

To change the Restart Time settings:

• From the Setup Operation Menu, choose Restart, as shown at

right, and press Enter ↵.

• To change the time delay in minutes and seconds (in the range of 00:00 to 99:59):

• For minutes (MIN), press and hold one of the arrow keys scroll through the numbers 00-99.

7.10.6 Specify Staging

Staging allows a standby device to be turned On when a sensor detects a monitored point reaching a specified setpoint. The AC8 continues to turn On additional standby units, if available, at specified intervals.

Staging also turns Off devices as the condition returns to normal. Devices are turned off in a last-on / first-off order, triggered by decreases of half the specified sensitivity increment.

The following example illustrates the staging process for a temperature sensor with a Target setpoint of 70°F and a Sensitivity increment of 5°F.

Temperature Reaches Target Level: First Device Turned On

• When the temperature in Zone 1 reaches 75°F (target plus sensitivity), the AC8 turns On a cooling unit that has been on standby.

Temperature Rises by Sensitivity Increments: Second & Third Devices Turned On

• When the temperature reaches 80°F—an additional 5°F—the AC8 turns On a second standby cooling unit.
