2.6 Battery Types  
This charger is suitable for use with all 24V, 12 cell, rechargeable lead acid  
batteries with capacities of approximately 200Ah.  
2.7 Charge Cycle Profile  
The Model 1620 charger provides three different charge profiles: IVa (Off Mode,  
see Figure 1), I VI a (Equalize Mode, see Figure 2) and IV V (Float Mode, see  
1
2
1 2  
Figure 3).  
For definitions of the variables mentioned in this section, refer to Table 1.  
page 2  
Curtis 1620 Manual  
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 will increase current to Constant Current value (Icc).  
This is beginning of a bulk charge, which typically returns 80% of the charge. At  
the end of bulk charging, battery voltage has reached Constant Voltage level (Vcv)  
and the charger will maintain the voltage by reducing the current (I) gradually.  
When the current drops to Icv, charging will stop, at which point the charger has  
returned 105-110% of the Ampere-hours discharged.  
If the battery is not used, its voltage will slowly drop due to self-discharging.  
When battery voltage reaches Restart Voltage (Vrst), the 1620 will turn back on  
and fully charge battery again.  
page 3  
Curtis 1620 Manual  
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 will set itself  
to Off Mode; the charger remains in standby until restart voltage (Vrst) is reached.  
page 4  
Curtis 1620 Manual  
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 will go through bulk charge and Constant  
Voltage modes as previously described. It then goes into standby until the battery  
voltage drops 0.4V below the Float Voltage (Vfloat, default value of 26.8VDC in  
Basic Mode) setpoint. The charger will then reactivate and maintain float voltage  
as long as the current requirement is above 2A. If current drops to 2A, the charger  
will again enter standby mode. The charger will continue this cycle of standby/  
reactivation until power is removed or until the Model 1311 programmer is con-  
nected.

INSTALLATION  
3.1 Unit should be securely mounted to a flat surface.  
3.2 The power cord to the IEC 320/C14 connector should be of the appropriate  
gauge to carry a 15A current, for the cable’s length, to meet the requirements  
of applicable electrical codes. The power cord must meet IEC requirements  
with a minimum cross section of 1.5mm.  
3
3.3 The wires between the charger output and the battery should be of the  
appropriate gauge to carry a 20A current, for the cable’s length, to meet the  
requirements of applicable electrical codes. An inline fuse (32V min. 30A  
max.) is recommended to protect against accidental battery short circuit.  
3.4 A minimum of 30mm clearance should be provided at each vented end of  
the charger.  
3.5 Charger should not be installed in locations which restrict airflow to the  
unit.  
3.6 The circuit supplying power to the charger should be rated at a minimum of  
15A for a 120VAC circuit, or for 5A for a 230VAC circuit.

Curtis 1620 Manual  
OPERATION  
4.1 Charging the battery  
4.1.1 If using the motor speed controller inhibit, and a Curtis motor controller  
is present, connect the Motor Controller Inhibit connector to the  
appropriate connector on the motor speed controller.  
4
4.1.2 Connect the (–) terminal of the charger to the (–) terminal of the battery.  
4.1.3 Connect the (+) terminal of the charger to the (+) terminal of the battery.  
4.1.4 Plug the charger into an appropriate AC power source.  
4.1.5 Charging is complete when a steady green indicator light is seen next to the  
battery symbol on the charger. Unplug the charger from the wall and  
disconnect the charger from the battery, removing the connection to the (+)  
terminal first.  
4.2 Programming Options  
Curtis chargers do not use the 1311’s Monitor, Faults, or Functions Menus. The  
Information and Programmer Setup Menus operate as described in the 1311’s  
instruction manual with the exception of the Serial Number submenu in the  
Information Menu – this field is filled with a default value of 12345678.  
The 1620 offers two levels of programmability, Basic and Advanced. The pro-  
gram features are accessed by connecting a Curtis Model 1311 handheld pro-  
grammer to the Programming port. Programming in Basic Mode involves setting  
battery type (Flooded or Sealed Lead-Acid) and End of Charge Mode (charge  
profile), while Advanced Mode offers flexibility of changing the most important  
parameters of the charger for optimum charging of almost any Lead-Acid based  
battery. Of course, selecting the Factory Default option restores the charger set-  
tings to the default values it left the factory with. This option can be invoked at  
any time.  
Variable parameters, limits, default settings, accuracy and descriptions are listed  
in Table 1.  
4.3 Programming the charger  
Note 1: Connecting the Model 1311 handheld programmer to the charger will  
cause the charger to enter standby mode while connected. The charger will reset  
and resume normal operation upon removal of the 1311.  
Note 2: The Model 1311 handheld programmer is available with different con-  
nectors. Be sure to use a 1311 with the 4 pin Molex connector. Conact a Curtis  
sales office for assistance.  
4.3.1 Attach the programmer to the 4-pin Molex connector, between the  
indicators. The yellow and green indicators will blink on and off  
simultaneously, indicating that the charger is in programming mode.  
4.3.2 Configure the programmable parameters defined in Section 4.2.  
4.3.3 Once the programmable parameters have been defined, disconnect the  
1311 programmer from the charger. The charger will reset and resume  
normal operation.

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  
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  
Replacing the fan:  
6.1.1. Disconnect the charger from power and from the battery.  
6.1.2. Remove the fanguard by simultaneously pushing in the retaining clips  
on either side of the fan and gently pulling the fan guard away.  
6.1.3. Unplug the fan assembly, noting the fan orientation, air flow direction,  
and wire routing.  
6.1.4. Remove the fan assembly.  
6.1.5. Replace with new fan assembly , being sure to match the orientation  
and airflow direction of the previous fan, and plug the fan in. Route  
the fan wires as previously located to avoid pinching the wires.  
6.1.6. Replace fan guard and push until a click is heard. Verify both retaining  
clips have fully engaged.
