4.1AS400 Interface Board (#100215120003)

4.1.1AS400 Interface Board Outputs

The AS400 Interface board connects the five most operationally critical UPS alarms to an IBM AS400 computer, which is designed to monitor such alarms and respond to their appearance:

*Mains failure

*Load on inverter

*Low battery and/or battery circuit breaker open

*Load on mains (bypass)

*Load on maintenance bypass

These alarm signals are provided by volt-free relay contacts.

The AS400 Interface Board is fitted to the bottom of the UPS cabinet door and connected to the UPS control electronics by a ribbon cable (FC17 in 25-40 kVA modules and FC13 in 50-125 kVA single phase modules) which is fitted to all modules and normally stowed in the cable loom when this option is not used.

Two D-type connectors are provided on the Interface Board to enable the above signals to be connected to the AS400 computer. One connector, CN1, has 9 pins and the other, CN2, has 15. Figure 21 provides pin-out details for these connectors.

Note: Use one connector only -i.e. don’t use both connectors simultaneously.

In addition to the D-type connectors, the AS400 Interface Board also contains a number of volt-free relays whose contacts provide a duplicate set of volt-free alarm outputs that are connected to terminal block M1 -as shown in figure 21. These outputs can be used to drive an external alarms monitoring device.

Note: When using the above contacts for remote alarm annunciation, the power supply for the remote indicators must be provided from an external power source. Under no circumstances should the UPS internal low voltage supplies be used for this purpose.

4.1.2Remote Control Inputs

4.1.3 Calibration

The Interface Board has facilities to accept two remote control inputs, as shown in figure 21. One remote input allows the inverter to be shut down (transferring the load to the bypass supply) and the other enables the inverter synchronisation feature to be inhibited. This facility is valid only for single module. The inverter synchronisation inhibit feature is most often used if the UPS is powered from a standby generator when the input mains supply fails and the generator frequency is unstable.

The external control signals (12V/ 24V) should be connected to terminal block M2 as shown in figure 21. Once again, the voltage supplied to these terminals must be generated by an external power source and not taken from the UPS internal low voltage supplies.

When fitting the AS400 interface board to the 7400 series, ensure that link SH - 1 is in position 1 - 2.
