Product Description

The VGLS9901I dry contact card provides dry contact signals for remotely managing the Easy UPS. To meet different application requirement, you set the signal (active open or active close) status on the card by setting jumper. The card is applicable in the following applications:

  • IBM servers, PCs, and workstations equipment.
  • Automatic control industry equipment and communications applications.

Pin Assignment

Pin # Function I/O
1 UPS Failure O/P
2 UPS Audible Alarm O/P
3 GND (Common for Pin 4) Power Ground
4 Remote Shutdown I/P
5 Common for Relays Power Supply
6 Bypass Active O/P
7 Low Battery O/P
8 UPS On O/P
9 Utility Failure O/P

P.S. The shutdown pin (pin4 & pin3) only accepts 3-10s high level signal to perform the UPS shutdown actions after shutdown delay (It depends on UPS Setting and default setting is 180 seconds). Remote shutdown is only effective in battery mode, and the UPS will auto-restart at AC recovery. Dry Contact Card VGLS9901I

Note: It’s required to retain the DC current lower than 6mA. Otherwise, it’s necessary to add one resistor within DC current limitation in the serial loop of Remote Shutdown. (e.g. 2K resistor with at least 0.1W rating power). Refer to diagrams in Application.

Installation

Install the dry contact card
You do not need to turn off power to install the dry contact card in a supported Easy UPS.
The Dry Contact Card is sensitive to static electricity. When handling the Dry Contact Card, touch only the end plate while using one or more of these electrostatic-discharge devices (ESDs): wrist straps, heel straps, toe straps, or conductive shoes.
For the location of the UPS Intelligent Card Slot, see the UPS User Manual.

  1. Remove the cover of Intelligent Card Slot on the back of the UPS and retain the screws.
  2. Slide the card into the open slot and secure with the screws from step 1. (See below chart)Schneider Electric VGLS9901 Easy UPS Dry Contact Card - FIG4
  3. Use one 9-pin cable (not supplied) to connect UPS and equipment to implement the remote monitoring and control.

Settings

Jumper Setup
There are 6 jumpers on this dry contact card. There are AC and AO white silk printings on the top of each jumper to indicate pin1&2 in A.C and pin2&3 in A.O.

JP 3 Bypass (P6 on DB-9)
JP 4 Low battery (P7 on DB-9)
JP 5 Utility failure (P9 on DB-9)

Internal Circuit Logic
Internal IC controller controls 5 relays for actions depending on the UPS status. Active-Close (A.C) terminal and Active-Open (A.O) terminal of each relay connect to pin 3 and pin 1 of a 3-pin connector respectively.
The pin 2 of the 3-pin connector connects to the signal pin of the DB9 interface connector. The 2-pin jumper can be plugged to the 3-pin connector to either short-circuit Pin1 & Pin2 (A.C) or short-circuit Pin3 & Pin2 (A.O). Schneider Electric VGLS9901 Easy UPS Dry Contact Card -
FIG10

Accordingly, if pin 1 short-circuits with pin 2 via the jumper, the status of dry contact signal will be ACTIVE CLOSE. Refer to below chart. When the signal is active, the signal pin on the DB9 connector will connect with the common pin (pin 5) via the relay. Schneider Electric VGLS9901 Easy UPS Dry Contact
Card - FIG11

If Pin 3 short-circuits with Pin 2 via the jumper, the status of dry contact signal will be ACTIVE OPEN. Refer to below chart. When the signal is active, the signal pin on the DB9 connector will disconnect with the common pin (pin 5) via the relay. Schneider Electric VGLS9901 Easy UPS Dry Contact Card -
