CHAPTER 3: Installation and Configuration
3.2 The Setup Procedure
Installing and configuring a Local/Remote Electronic Switch is relatively quick and
easy, and will vary only slightly depending on which model you’ve chosen. Follow
these steps:
(Steps 1 through 4 are for
remotely switched applications
only:)
1. Make sure that the Switch is unplugged (is not receiving AC power). Open
the Switch by unscrewing the two screws on the bottom of the unit (save these
screws) and removing the top of the unit’s housing. (You will probably have
to peel back the CE sticker on the bottom of the unit to get at one of the
screws.)
2. Find jumper W1 (for SW980 or SW981 units) or jumpers W2 and W3 (for
SW982 units) on the Switch’s circuit board. Refer to Figure 3-1 on the next
page if your unit is an SW980 model, to Figure 3-2 on page 11 if your unit is
an SW981 model, or to Figure 3-3 on page 12 if your unit is an SW982 model.
Set the jumper(s) as appropriate for your application:
• Set W1, or W2 and W3, to the A-B position for applications that use
dry-contact closure to perform remote switching.
• Set W1, or W2 and W3, to the B-C position for applications that use
active driver(s) to perform remote switching.
