Introduction 1.0 INTRODUCTION The Liebert AC4 is ideal for coordinated control of systems with redundant equipment, such as multiple environmental units or pumps. When the Liebert AC4 controller detects an alarm in an operating device, the Liebert AC4 enables a standby device and controls the device in alarm as configured, either leaving that device operating or disabling it.
Introduction 1.4 Outside Enclosure Overview The Liebert AC4 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 Liebert AC4 enclosure—external features LCD for configuration and operation The enclosure has knockouts and access slots on top and bottom for cables and wires.
Introduction 1.5 Typical Configuration Figure 3 shows an example of external devices connected to the Liebert AC4 controller board. There may be up to four devices connected to the four digital inputs and four digital outputs. Remote access is available through the Service Terminal Interface.
Introduction 1.6 Controller Board Overview The Liebert AC4 controller board has connectors for four digital inputs and four digital outputs, as shown below. The board comes complete with light emitting diodes (LEDs) to display the status of connected devices, a serial communications port, a power connection and other features necessary to control your operation.
Introduction Table 1 Controller board components (continued) Item Description For more information, see: I - Digital output loss-of-power jumper One of four output jumpers. Each digital output has a jumper to set the fail-safe position of the output point when power fails. The OFF position makes the contact Normally Open (factory default). The ON position makes the contact Normally Closed. Note: The jumper position has no effect on the contact when the Liebert AC4 has power. 3.2.
Introduction 1.
Introduction 1.8 Typical Sequence Figure 4 shows a typical sequence of how the Liebert AC4 functions after detecting a change in a monitored device. Many responses depend on configuration settings. This example shows what happens when a digital input changes state—assuming the input is defined as alarmable—and when the condition returns to normal. Figure 4 Example of typical sequence RESPONSES TO AN ALARM UNIVERSAL MONITOR 05-SEP-02 14:04:13 V5.100.
Installation 2.0 INSTALLATION 2.1 Installation Considerations The Liebert AC4 must be installed indoors and may be mounted on the surface of a wall or flushmounted, depending on the user’s application, the location of equipment to be connected and the type of wall the unit will be mounted on. The Liebert AC4 should be mounted where it can be easily accessed. On-site personnel would access the unit through the LCD on its front cover or the service terminal connected to the RS232 port.
Installation 2.2 Surface-Mounting the Liebert AC4 NOTE Removing the conduit knockouts before mounting the Liebert AC4 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 • • • • 2.2.
Installation 2.3 Flush-Mounting the Liebert AC4 NOTE Removing the conduit knockouts before mounting the Liebert AC4 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. The rectangular access doors on the top and bottom of the Liebert AC4 must be reversed so they slide the opposite direction.
Installation 2.4 Connect Power to the Liebert AC4 The Liebert AC4 requires 24VAC for proper operation. Liebert recommends using the optional Transformer Module manufactured by Liebert or another UL-approved class 2 power unit to obtain proper voltage. If the power unit is not a class 2 circuit, it must be protected with an IEC 5 x 20mm time lag 2A fuse. For information, consult your local dealer, Emerson representative or the Emerson Network Power Liebert Worldwide Support Group.
Wiring and Connections 3.0 WIRING AND CONNECTIONS ! WARNING Risk of electric shock. Can cause property damage, injury and death. Switch Off electric power to the Liebert AC4 before installing any wiring to the unit or changing input or output connections. The Power On/Off switch is in the top left corner of the unit. 3.
Wiring and Connections 3.2 Connecting Digital Inputs and Outputs The digital inputs and outputs are on the lower right side of the Liebert AC4 printed wiring assembly board. This section describes how to connect devices to the Liebert AC4’s inputs and outputs.
Wiring and Connections 3.2.2 Connecting Digital Outputs The four digital outputs are found on the lower right side of the Liebert AC4 just above the input terminal blocks, as shown at right. These outputs are numbered 1 through 4. To connect an output: 1. Turn OFF electrical power to the Liebert AC4. 2. If necessary, remove a conduit knockout to permit wire entry into the Liebert AC4 enclosure. 3. Bring the wire(s) into the Liebert AC4 enclosure through a conduit knockout or access slot. 4.
Wiring and Connections 3.3 Connecting Common Alarm Outputs The common alarm relay, found in the top right corner of the Liebert AC4, permits the user to connect auxiliary notification equipment, such as lights, horns and sirens, to the Liebert AC4. To determine the proper wire size, see Table 4 Wiring specifications. There are two connectors for the common alarm output. However, the connectors are not individual relay outputs. The connectors should be treated as a double-pole, double-throw (DPDT) relay.
