WARRANTY
The instruments are warranted against defective materials and
workmanship for a period of three years from date of delivery.
If a product appears to have a defect or fails during the normal use
within the warranty period, please contact the distributor from which
you purchased the product.
This warranty does not apply to defects resulting from action of the
buyer such as mishandling or improper interfacing.
The liability under this warranty shall extend only to the repair of the
instrument. No responsability is assumed by the manufacturer for
any damage which may result from its use.
KOSMOS SERIES
1. INTRODUCTION
The isolator provides isolated re-transmission of the input signal, which
can (by internal selection switches), be set to accept and re-transmit most
common process signals. The isolator can either be DIN rail or surface
mounted.

3.0 CONFIGURATION
The isolator leaves the factory calibrated for the input output rates
specified ot the time of the order, if no ranges have been specified then
the isolator range will be 4-20mA in and out. If required the isolator ranges
may be changed by the installer, provided access is available to suitable
calibration equipment in order to simulate the required input/ output
signals. Configuration and calibration are best carried out prior to
installation. The isolator is configured by means of internal switches.
WARNING!
Extreme caution must be exercised when replacing the terminal housing.
Aling holes in front panel with trim pots and LED within. Failure to do so
may cause the installer to wire the unit incorrectly.
3.1 Configuration
WARNING! Mains power may be present. NEVER open the isolator
case when powered. Follow steps 1-4 to gain access to the internal
configuration switches.
1. Disconnect from all power sources.
2. Insert screwdriver to release clips either side of case.
3. Slide terminal housing assenbly forward to reveal circuit board and
configuration switches.
4. To identify switches read PCB copper text for SW1,SW2 and SW3.
5. To reassemble push circuit card back into shell (using clips
provided) and clip into place.
