3.0 COMMISSIONING
This chapter describes configuring, commissioning, and operating an ARE-Series 24V Charger. A front view of
a typical charger is shown in Figure 3-1. All operator controls are on the front of the charger.
FIGURE 3-1 OPERATOR CONTROLS
The front of the unit has a large, high-contrast 2-line digital display, a 4-button keypad with tactile feedback for
positive data entry, two LEDs for charger On/Off and alarm indications, and AC and DC circuit breakers. An
optional control board offers front panel indicators, consisting of a High Voltage Alarm, Low Voltage Alarm,
No Charger Alarm, AC Fail Alarm on the telecom models, and an additional Positive and Negative Alarm
indicators are on the utility models. A microcomputer-based controller manages charger operation. The keypad
and display provide the means for entering charger setup data (e.g. float voltage, high voltage shutdown, and
temperature compensation on/off).
IMPORTANT:
Press the keypad with your finger. Pressing with a sharp or pointed tool will damage the switch
overlay and can damage the switch itself.
The following two sections will describe charger commissioning.
PREPARATORY STEPS
3.1
Perform the following steps prior to actually commissioning a charger.
1.
Gather system wiring diagrams, battery data sheets, and other site documentation for ready reference should
it be needed.
2.
Check that all installation steps have been completed. Review Chapter 2 Installation. The system can be
commissioned with or without a battery string.
3.
If a battery string is connected to the charger, temporarily disconnect any external load connected to the
battery string.
4.
Review the steps in Section 3.2 Commissioning Procedure.
5.
Become familiar with the operation of the front panel and the setup menus by reading Chapter 4 Setup and
Operation.
6.
Read the two statements below to determine whether charger setup parameter values can be displayed and
edited prior to application of AC power to the charger. See Chapter 4 Setup and Operation for setup details.
Table 4-1 lists default parameters and values.
