APC VS 100 Operation, Description, Controller Card Jumpers, System voltage J5, Remote Lockout J8

6 Operation

6.1. Description

The Magnum VS is designed for years of operation with no user input. The power system is pre-programmed at the factory with all parameters needed for normal operation. The front panel LEDs and the alarm output relays, indicate the general health of the unit. There are 2 controllers available for this power system. A LCD display with keypad (0M-2997) will access most operator functions from the front of the unit. This controller is described in more detail in Section 6.3. A controller without display (0M-1650) is described in more detail in Section 6.5. This controller requires local parameter changes to be made using a PC.

6.2. Controller Card Jumpers

System voltage J5

The positioning of jumpers on header J5 will determine the operating voltage of the controller card operates. Options include –48 V, +24 V, +48 V, or –24 V systems. The Magnum VS is only a –48 V system. The only setting allowed is the –48 V setting, which is J5-1 jumpered to J5-6 and J5-2 jumpered to J5-7.

Remote Lockout J8

It is possible to make parameter changes to the controller card through the RS232 port or through the 10/100 Base T port of the network management card. The controller card is shipped with a jumper between pins J8-2 and J8-3, allowing such parameter changes. If the user wishes to disable the remote configuration feature, then the jumper is moved to pins J8-1 and J8-2.

Firmware Programming Enable J9

When the operating system is initially installed at the factory, J9-1 is jumpered to J9-2. This setting interferes with normal operation. To ensure normal operation, the controller card is shipped without this jumper. During normal operation, the only setting allowed is no jumper between J9-1 and J9-2.

Vtrim Trip Select J13

The header J13 is a factory set header that allows this controller to work with different types of rectifiers. The Magnum VS always uses the Magnum VS rectifier. During normal operation, the only setting allowed is J13-2 jumpered to J13-3.
