Novus Micro Operator’s Manual 1.2 Unpacking and Inspection Checklist If items are missing or damaged, contact Alpha Technologies and the shipping company at once. Most shippers have a short claim period. Carefully remove the UPS from the shipping container. Inspect the contents and make sure the following items are included: 1 Novus Micro UPS. 1 Novus Micro Operator’s Manual. 2 or 3 terminal blocks and labels for the dry contacts. 1 temperature sensor cable. Any ordered options.
Introduction 1.3 The Novus Micro Family Figure 1.3.1 shows the three different enclosures, (1) the standard Micro, (2) the Micro XL, and (3) the Micro XL3. Each of these enclosures can be configured with the 300W, 600W or the 1000W power module (E-Module). Although the end system configuration may look different, the front panel connectors and circuit breakers along with the input and output terminal blocks are functionally the same. They all operate in the same way unless otherwise stated in this manual.
Novus Micro Operator’s Manual 4 1 13 3 2 Figure 1.3.3 – E-Module Control Panel Description 1 Battery Circuit Breaker This circuit breaker provides overcurrent protection and is an on/off switch for battery power. It must be on for proper UPS operation. 2 Battery Connector This connects the batteries to the UPS. 3 Internal Fan This microprocessor-controlled fan regulates the UPS’s internal temperature for optimum performance. It must not be blocked.
Introduction 5 LCD Control Panel (1000W version only) This panel and the CANCEL, SCROLL and SELECT buttons below it let you monitor and control the UPS. More information is given in Section 3, “Operation.” 6 Battery Voltage Test Points (1000W version only) These let you measure the battery voltage. They accept 2mm diameter test probe tips. The battery circuit breaker must be on to measure the voltage. NOTE: It is not a power outlet.
Novus Micro Operator’s Manual 10 ATS C8 When the UPS is in Inverter mode, the normally open relay closes (Figure 1.3.6), sending 48VDC or 24VDC from the batteries to this dry contact (See Section 2.3). Note: This contact can be used to power any external logic circuits or loads when the UPS is in Inverter mode. 48VDC or 24VDC from the batteries Microprocessor + Figure 1.3.
Introduction 14 Dry Contacts (Models 300 & 600 only) Contacts C1 and C2 allow you to connect the UPS to an external monitoring panel or to traffic control equipment. The factory default settings are given below, but you can program them to meet your requirements (See Section 4.4, “Programming the Dry Contacts” or Section 4.6, “Novus Micro Graphical User Interface”. Figure 1.3.8 shows the contact’s layout.

3 Operation This Section Tells You How to Operate the Novus Micro • Turning the UPS On and Off (Section 3.1) • Operating the Control Panel (Section 3.2) • Replacing the Batteries (Section 3.3) • • Operating the UPS (Section 3.4) Making Measurements (Section 3.5) • • 20 Troubleshooting (Section 3.6) Viewing the 25-Event Log (Section 3.
Operation 3.1 Turning the UPS On and Off If the UPS constantly switches between Inverter and Line modes due to a noisy line, the UPS’s input parameters should be broadened from normal to generator (See Section 3.4, “Operating the UPS,” “Sense Type”). In generator mode, the range of acceptable input frequency and voltage is expanded to accept the fluctuations created by a generator . 3.1.1 Turn On This procedure assumes the line is qualified and the batteries are fully charged.
Novus Micro Operator’s Manual 4. Turn on the input circuit breaker. The LCD displays RETRAN, then shows LINE, or BUCK or BOOST. The status LED turns on. Turn On Finished 3.1.2 Turn Off 1. Turn off the input circuit breaker. 2. Turn off the battery circuit breaker. The status LED is off and the LCD panel is blank. Turn Off Finished LED Descriptions LED Description GREEN OFF The UPS’s inverter is turned off. Line power goes straight to the load. GREEN ON The UPS is turned on.
Operation 3.2 Operating the Control Panel For Model 1000, the LCD control panel has a 2x20-character backlit alpha-numeric LCD screen. It provides “at a glance” monitoring, and displays status, event, alarm, fault and control UPS functions locally. When used together with the CANCEL, SCROLL and SELECT buttons below it, the control panel lets you program, make measurements and troubleshoot the UPS. The layout is shown below in Figure 3.2.1 below. For Models 300 and 600, see Section 4.
Novus Micro Operator’s Manual Pressing the CANCEL, SCROLL and SELECT buttons let you to navigate through the menus and submenus to control, monitor and troubleshoot the UPS as shown in Figure 3.2.3 below.

SELECT Control Menu (Section 3.4) SCROLL TWO: Press the SCROLL button to move between the menus.
Operation 3.3 Replacing the Batteries While the batteries are being replaced, the UPS cannot provide backup battery power. This procedure should NOT be done when critical loads are running that depend on this unit for backup power. Procedure 1. For Model 1000, if the UPS is in Line, Buck or Boost mode (See Figure 3.2.2) go to the control submenu to switch it into Inverter Bypass (See Section 3.4 also see the Control Panel Tutorial in this section).
Novus Micro Operator’s Manual 3.4 Operating the UPS For Model 1000, the control menu (Figure 3.4.1) lets you operate the UPS or program it to suit your operating conditions. You can also use the Novus FXM Monitor software to make these adjustments (See Section 4.6, “Novus FXM Graphical User Interface”). For Models 300 and 600, see Section 4. Procedure 1. From the logo screen (See Figure 3.2.1) go to CONTROL MENUS (See Figure 3.2.3). 2. 3. 4. Press the SELECT button to enter the submenu (See Figure 3.4.
Operation Control Menu LCD Shows Meaning Description INVERTER Inverter When turned on, this forces the UPS to provide backup battery power to the load. This is usually activated when the UPS is turned on and there is no line power available. INV BYPASS Inverter Bypass This function can only be turned on when the UPS is in line mode. When turned on, this locks the UPS into line mode and makes the output voltage equal to the input voltage. This is done to: Replace the batteries (See Section 3.3).
Novus Micro Operator’s Manual 3.5 Making Measurements The System Status Menu (Figure 3.5.1) on Model 1000 lets you make measurements of various UPS inputs, outputs, temperatures and other values. On all models, you can use the Novus FXM Monitor software to make these measurements (See Section 4.6, “Novus FXM Graphical User Interface”). Procedure 1. From the logo screen (Figure 3.2.1) go to the system status menu (Figure 3.2.3). 2. Press the SELECT button to enter the submenu (Figure 3.5.1). 3.
