Epoch-S02 RF Repeater
User Manual V1.1
heartbeats being sent include consistent Hard Failure (as mentioned in the “Alarms”
Section 2.3) in the following areas:
1. Over Current
2. Over Power
3. Over Temperature
Over Current
The “Over Current” Alarm occurs when the input current from the power
source exceeds 6 Amps. In order to lessen the amount of Amperes
drawn by the Epoch-S02, the control board will shut off components that
draw current (i.e. the HPA).
Over Power
The “Over Power” limits for uplink and downlink are set by the user in the
Alarm Setting Window in the Control Menu. A Hard Failure “Over Power”
Alarm occurs when the output of the Epoch-S02 exceeds the limits
entered into the Alarm Parameter Settings (Over Power limit +1 dBm).
Over Temperature
A temperature inside the box greater than 185º F will cause the Epoch-
S02’s control board to shut down the HPA in an attempt to lower the
temperature inside. Though the Epoch-S02 is equipped with a heat sink
to dissipate heat, extreme conditions, such as very hot temperature, are
dealt with by shutting down heat-generating components (i.e. HPA).
1. Prior to visiting the site, know the temperature of the Epoch-S02 site
on the day that the heartbeat stopped being sent.
2. Observe the ambient temperature surrounding the Epoch-S02 site. If
the weather is hot, it is safe to assume that the outdoor temperature
caused the “Over Temperature” Failure.
3. If the outdoor temperature was or is fairly cool, one can assume too
much heat is being generated within the Epoch-S02.
4. Since the HPAs have been shutdown to dissipate heat, it is safe to
evaluate the repeater by unlocking and opening the front door.
5. Evaluate the inside of the Epoch-S02 and check to see that no
unusual wear exists (e.g. burned, blackened areas, etc.). If you detect
these areas, contact Advanced RF Technologies, Inc. in the “Warranty
and Contact Information” section, Section 5.
