Rotem One Winch Card Set Replacement

Introduction

Figure 1: Rotem One Cards and Switches

General

A Winch Card set (10 relays) consists of the following:

• One Winch Relay Card (five relays)
• One Switch Card
• One Normally Open Relay Card (five relays)
• The Winch Relay Card is always installed on the right side.
• The Normally Open Relay card is always installed on the left side.

Figure 2: Relay Card showing Jumpers

If there is no jumper installed on the card, the card fuctions as a Normally Open card.

For the Winch Card set to function as a Winch Card, jumper must be installed properly on the Normally Open Card.

In Practice

• When a customer orders a Rotem One unit that includes a winch card, the Normally Open card comes installed as required, including the requisite jumper.  In addition, the card comes in place if a dealer technician assembles a Rotem One unit according to the customer’s specifications.
• In cases where a someone orders a (replacement) winch card set, the customer/dealer must properly place the jumper in place on the Normally Open (before installing the card) for the winch card to operate properly
  • Solder a jumper to J3
  • Refer to the following drawing.

Relay Card Layout Considerations

• When installing or replacing Normally Closed cards, all ten relays in any given row must be Normally Closed cards.
• When installing or replacing Normally Open cards, all ten relays in any given row must be set to Normally Open UNLESS the Normally Open Winch Relay Cards are used.
