4 Introduction
The Monitoring and Control System is an end to end solution for the rf-system in the broadcast
towers. With the Monitoring and Control System the operator can detect and prevent
malfunctions, increase the safety and manage third party situation (outsourcing, colocation):
With the Monitoring system, the broadcast tower operator is able to:
do preventive maintenance and prevent from partial/total system failures
minimize SLA violation caused by “slow death” effects (like water in the system,
mechanical abrasion)
safe time and cost for failure detection because of direct failure localisation
safe time and costs to repair because the correct spare material is on site
safe fixed costs because of central dispatching and optimized maintenance team
assignment
Increase the security of broadcast towers (prevent from fire and successive failure
damage)
Offer a monitoring service to partner, operators or broadcasters
Prove SLA compliance
Manage third party or outsourced services by detecting power level and measure return
loss / VSWR
Increase the safety of the RF-system by controlling the transmitters with
4.1 Purpose of the Document
This user manual helps the operator to install and configure the Data Logger and Tower Meter
as part of the commissioning activity, look up the monitoring results (Dashboard and trend
curves) and manage the alarms.
The Data Logger/Tower Meter (DL/PDL) connects to the outdoor Junction Box (JB 3.x) with a
hybrid cable. The hybrid connector Han-Brid connects to the hybrid cable, see chapter 8. The
indoor Junction Box (JB 4.x) is connected with a standard Sub-D 9 pole cable. Each JB can be
operated in a daisy chain mode.
Before starting any installation actions, we ask the user to read carefully the safety instructions
in chapter 6. These instructions need to be strictly followed.
4.2 Scope
This manual describes the installation of the Data Logger (DL) and Tower Meter (PDL) at the
transmitter location in the Infrastructure room of the tower facility.
After the installation of the Sensor or RF-/Temp. -Detectors and Junction Box and the related
cabling in the tower, the DL/PDL is put into operation.
This manual explains the system configuration, alarm management and dashboard functionality
(incl. trend curves).
