2.7.1 – End of Charge Mode Figure 1. Charge profile for End of Charge Mode Figure 1 defines the charge profile for the End of Charge Mode. As long as the battery voltage (V) is above Undervoltage Lockout Level (Vuvlo), charging will start after short delay of about 6 seconds. For battery voltage between Vuvlo and Vlv, charge current will be limited to lower value (Ilv) in order to prevent gassing damage to the batteries. Good batteries will quickly increase voltage above Vlv and the 1620 wi

2.7.2- Equalize Mode after End of Charge Mode Figure 2. Charge profile for Equalize Mode Figure 2 defines the charge profile for the Equalize Mode. After going through bulk charge and Constant Voltage modes, the charger will reduce its output cur- rent to Top-Off Current (Ito) until one of the two possible outcomes occurs: (1) Battery voltage rises to Equalize Voltage (Vequ) or (2) Equalize Time-Out (Tto) is reached. Once one of these two possibilities occur, charging will stop and the 1620 wi

2.7.3 - Float Mode Figure 3. Charge profile for Float Mode Figure 3 defines the charge profile for the Float Mode. In this mode of operation, batteries are maintained at full charge. In addition to maintaining full charge, the charger can support a load current – as long as the combined load current and battery charging requirements do not exceed the output current defined in the Constant Current setpoint (Icc, default value of 20A in the Basic Mode). In this mode of operation, the charger

MAINTENANCE Excess dirt or grime may be removed from the unit by wiping it with a cloth dampened with water. Although Curtis chargers are equipped with a fan designed to last the life of the 6 charger, exposure to harsh environments – such as dusty condition, grease, chemi- cals, etc. – may impair the effectiveness of the fan. If the operation of the fan is noticeably degraded, Curtis recommends an immediate replacement of the fan with Curtis Part Number 17603351, 1620 Fan Assembly. 6.1 Rep
