Det-Tronics EA2100CG Eagle 2000 Communication Gateway - Manual (Page 40)

CAUTION
The O-ring should be lubricated with a silicone free
polyalphaolefin grease. The use of other lubri-
cants is not recommended, since they can
adversely affect the performance of some sensors.
Under no circumstances should a lubricant or com-
pound containing silicone be used on systems
using catalytic type combustible gas sensors.
SENSOR REPLACEMENT
Declassify the area or remove power to the detector
prior to replacing the sensor in a hazardous area.
To replace the sensor:
1. Remove the cover from the communication module
enclosure and press the sensor replacement switch
on the circuit board. The calibration bit is set in the
status word.
Pressing the sensor replacement switch prevents
the communication module from generating a fault
signal when the input drops to zero due to removing
the sensor. In addition, the calibration will not be
aborted if the calibration procedure is not complet-
ed within 12 minutes.
2. Replace the sensor or sensing element.
3. Calibrate the sensor using the normal calibration
procedure.
NOTE
Compare part numbers to be sure that the correct
replacement sensor is being used.
REPLACEMENT PARTS
Eagle devices are not designed to be repaired in the
field. If a problem should develop, first carefully check
for proper wiring, programming and calibration. If it is
determined that the problem is caused by an electronic
defect, the device must be returned to the factory for
repair.
NOTE
When replacing a device, be sure that the rocker
switches on the replacement are the same as the
original. Remove power before removing or plug-
ging in the replacement unit. When a communica-
tion module or DCU is replaced, the type and con-
figuration codes must be down loaded.
DEVICE REPAIR AND RETURN
Prior to returning devices or components, contact the
nearest local Detector Electronics office so that an RMI
(Return Material Identification) number can be assigned.
A written statement describing the malfunction must
accompany the returned device or component to expe-
dite finding the cause of the failure, thereby reducing the
time and cost of the repair. Pack the unit or component
properly. Use sufficient packing material in addition to
an antistatic bag or aluminum-backed cardboard as pro-
tection from electrostatic discharge.
Return all equipment transportation prepaid to the
Minneapolis location.
