Introduction 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.
PAGE 10
Introduction 1.5 Outside Enclosure Overview 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 LCD for configuration and operation The enclosure has knockouts and access slots on top and bottom for cables and wires.
PAGE 11
Introduction 1.6 Typical Configuration 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.

System and Control Options 7.9.10 Initiate Remote Alarm Test (Service Terminal Interface only) The service phone number is used for remote monitoring by Liebert Global Services. The Service Terminal Interface may be used to test communications between the AC8 and the service modem. This test will send a “DIAL OUT TEST PASSED” message to the service phone number.
PAGE 76
System and Control Options 7.10 Setup Operation The AC8’s operation features allow you to set up a rotation sequence to Setup System Menu alternate which devices are operating and which are placed on SETUP INPUTS Standby, as well as test devices while in Standby mode and specify SETUP COMMON ALARM what to do when a Standby device goes into alarm as it is powered up.
PAGE 77
System and Control Options 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.
PAGE 78
System and Control Options 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.
PAGE 79
System and Control Options 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).
PAGE 80
System and Control Options 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.
