“WIRELESS” OLCT200/RF900 & WX4 QUICK START GUIDE
WARNING! This Quick Start Guide is provided as basic instructions for commissioning a wireless network
consisting of up to four OLCT200/RF900’s and an WX4 Controller. Gas sensor operation is not discussed in
this guide. READ & UNDERSTAND ALL OPERATIONS MANUALS FOR SAFE OPERATION!
Test ALL operating parameters with transceivers in close proximity prior to their final installation!
WX4 Controller Configuration:
First - apply power to an WX4 Controller equipped with the 10-2454 Wireless interface (antenna port visible on top).
Press EDIT to reach SYSTEM SETUP and use Set Channel & Input Type menus to configure WIRELESS
channels (Figure 1). Rmt Xmitter ID sets which OLCT200/RF900 address provides data to this channel.

From SYSTEM SETUP use Communications to access
COMM SETUP menus and confirm Wireless Receiver is
indicated (Figure 2). Check the Configure Radio settings.
Hop Channel and System ID are factory settings and should
not be altered without a detailed understanding. If the network
has only one WX4, it’s Mode setting must = Server If there .is
more than one WX4, the most centrally located should be Server
and the others Clients
.
Confirm after 18 minutes all WIRELESS channels indicate
CE -Comm. Error (Figure 3). The 30-minute trend screen
offers a useful tool for wireless channels. An arrow moves
from right to left during transmission intervals. OLCT200/RF900’s
transmit gas values each 5-minutes with no alarm and each 6seconds with alarms. Properly functioning channels will show the arrow
progressing to the 5-minute marker and resetting back to the far right. Channels
with ComErr’s show the arrow stopped at the 18-minute point (as shown). An Rx
LED at lower right of the WX4 display PCB flashes each time a wireless channel
receives data from a OLCT200/RF900.
OLCT200/RF900 Sensor Transmitter Configuration:
With the WX4 showing CE -Comm. Error on each channel configured for WIRELESS
power switches. Unscrew
inputs, apply power to each OLCT200/RF900 by turning on the
the XP cover, loosen the two thumbscrews, gently remove the front panel, turn power
switch to ON position, replace the front panel and thumbscrews (Figure 4).
Observe “Radio Status Icons” to see if a “Server In Range” icon appears each 6seconds (Figure 5). If “Server Out of Range” icon appears, use the EDIT key to
enter the menus, select Communications. Confirm Hop Channel and
System ID factory settings match these values in the WX4 Controller
(Figure 2). The Rmt Xmitter ID must match the desired channel destination of
the Rmt Xmitter ID since this determines which WX4 channel displays
this transmitter’s data.
OLCT200/RF900 Transmission Frequency and Battery Life:
FIGURE 5
FIGURE 6
A1 & A2 level alarms cause RF transmissions to increase from each
5-minutes to each 6-seconds. The front panel TXD LED flashes
with each RF transmission. Transmissions may be forced by holding
the UP key for 10 seconds. Transmissions also occur at the
beginning and end of calibrations. Expected battery life is 9-12
months in normal operation. Avoid prolonged alarm intervals for
optimal battery life.
Set gas alarm set-points at the correct alarm levels. Oxygen
monitors must be set for “low trip” to avoid constant alarm
conditions. Missing sensors create constant FAULT alarm
conditions.
