Chassis. Two Thumb Screws can be loosened to facilitate removal of the Card Edge Cover,
and thus accommodating all instrument field wiring. Information on mounting the
ControlWave Express assembly is provided in Section 2.3.1 Mounting the ControlWave
Express.
2.2.1 Temperature & Humidity Limits
ControlWave Express RTUs have been designed to operate over a -40°F to +158°F (-40°C
to +70°C) temperature range (with storage at up to +185°F (+85°C)) and a 0% to 95%
relative humidity range. Make sure that the ambient temperature and humidity at the
measuring site remains within these limits. Operation beyond these ranges could cause
output errors and erratic performance. Prolonged operation under extreme conditions could
also result in failure of the unit.
2.2.2 Vibration Limits
Check the mounted enclosure, panel or equipment rack for mechanical vibrations. Make
sure that the ControlWave Express is not exposed to a level of vibration that exceeds those
given in the specifications. ControlWave Express vibration limits are 1g for 10 - 150 Hz &
.5g for 150 - 2000 Hz.
2.3 ControlWave Express INSTALLATION/CONIGURATION
Overview of Configuration
An overview of the main configuration steps are provided herein.
Step 1. Hardware Configuration
This involves unpacking the ControlWave Express hardware, mounting the
enclosure/chassis, wiring I/O terminations, connecting any permanent communication
cables, making proper ground connections, connecting a communication cable to a PC
workstation, setting switches and setting jumpers. To install and configure the
ControlWave Express, follow the steps below:
1. Remove the unit from its carton and install it onto a panel or DIN-rail in an
appropriate enclosure and then ultimately at the assigned work site (see Section
2.3.1). Dimensions are provided in Section 4.6 of this manual.
2. Remove the Process I/O Board and the CPU/System Controller Board (as one
assembly).
3. Make sure that the Lithium Backup Battery has been enabled, i.e., Backup Battery
Jumper W3 on the CPU/System Controller Assembly should be installed on jumper
posts 1-2). Configure the CPU/System Controller Board DIP-Switches and Jumpers
(see Sections 2.3.3 & 2.3.3.1). Configure the Process I/O Board’s DIP-Switches and
Jumpers (see Section 2.3.2). After configuring the Jumpers and DIP-Switches,
install the Process I/O Board and the CPU/System Controller Board (as one
assembly) into the enclosure.
4. Configure/Connect appropriate communication port(s) (see Section 2.3.3.2). Connect
COMM. Port 1 or 2 of the ControlWave Express (depending on CPU/System
Controller Board Switch SW2 settings - see Section 2.3.3.1) to a Communication Port
of a PC (typically PC COMM. Port 1). Note: Also see Section 2.4.4.
