EATON 777387 Relay MS Card
USING THE CARD WITH A SINGLE-PHASE UPS
INTRODUCTION
The Relay Card – MS offers two types of interfaces via a DB9 connector:
- Dry contacts (contact mode)
- RS232 serial interface (RS232 mode)
All UPSs from EATON equipped with a Mini slot can be connected to a number of electrical-management applications. Jumpers are used to select the interface (contacts or RS232).
APPLICATIONS
Contact mode (factory setting)
- In this mode, the card provides a simple way to remote UPS information to an alarm system, PLC, or computer system via dry contacts (relay).
- The transmitted information is load powered, load on bypass, load on the battery, load on utility, battery fault, and low battery.
- A UPS power-off function activated by an external contact or voltage level is also proposed. It is available only in contact mode.
- Equipped with an IBM iSeries or Windows cable available from EATON, the card offers direct communication with the power management system of the servers supplied by the UPS and can thus provide protection (shutdown) on the reception of one of the information signals. Configuration of the various systems is presented in the documents supplied with the cable. For this application, use the Config2 setting on the card.
RS232 mode
- In this mode, the card offers an RS232 interface for connection to a PC. Connection to a PC requires the RS232 UPS Communication Cable. The cable is not supplied with the card. Once connected the protection software can be installed and used immediately.
- The WindowsTM Plug&Play function is managed by the card.
- The cable is available from EATON.
UNPACKING AND CHECKS
- One Relay Card – MS
- One installation manual (34003907)
OVERVIEW
CONTACT MODE CONFIGURATION
- In this mode, the contact (relay) is closed between the common (pin 5) and the pin transmitting the signal (pin 2, 4, 6, 7, 8, 9) when UPS information is active or true.
- When the card is not supplied, all the contacts between pin 5 and the other pins are open, except the contact between pin 4 and pin 5, which remains closed.
- Three configurations are available in this mode, for three types of UPS power off. The diagram below shows, for each configuration, the jumper settings, the various contacts (card not supplied), and the external wiring for the power-off function. The UPS shuts off if the contact position is the opposite of that shown.
DB9 CONNECTOR PINOUTS
| No. | Function | Description |
|---|---|---|
| 1 | Not used | |
| 2* | Battery fault (Config 2) UPS power off (Config 1 or 3) | Config 2 : a |
battery fault occurred.
Config 1 or 3 : UPS power off by contact.
3| UPS power off (Config 2) Not used (Config 1 or 3)| Config 2 : UPS
power off by voltage level.
4| Load on utility| The load is protected. The UPS supplies the load using
utility power (not from the battery).
5| Common| Config 2** : volt-free pin.
Config 1 or 3 : pin connected to GND.
6| Load on automatic bypass*| The load is not protected. The UPS supplies
the load using utility power. If utility power fails, the load will not be
supplied.
7| Low battery| The battery has dropped below the preset warning level
(depending on UPS setup). If the voltage level continues to drop, the UPS will
no longer be capable of supplying power to the load.
8| UPS ON, load powered| The UPS is operational and can supply power to the
load, whether utility power is available or not, whether the UPS is on the
bypass or not.
9| Load on battery | The load is protected. The UPS supplies the load from
the battery (not using utility power).
The function of this pain varies, depending on the configuration. The Battery fault information is available only in Config 2.
- Load on utility and Load on the battery are complementary signals. They cannot be activated simultaneously.
- Not available online-interactive UPS. No manual bypass.
RS232 MODE CONFIGURATION
- In this mode, only one configuration is possible
DB9 CONNECTOR PINOUTS
| No. | Function | Description |
|---|---|---|
| 2 | TD | Transmit data (output) |
| 3 | RD | Receive data (input) |
| 5 | GND | Ground |
| 6 | RTS | Plug-&-Play (input) |
| 1, 4, 7, 8, 9 | Not used |
INSTALLATION
The Relay Card – MS can be installed on a running UPS from EATON compatible with this card. It is not necessary to shut off the UPS, disconnect the load, or restart the UPS.
- Remove the plastic cover of the Mini slot.
- Insert and secure the card with the screws.
