11.2.2
Semi-annual maintenance includes:
-
monitoring of the charger external cables status;
-
lubrication of the pole rubbing elements.
11.2.3
Check that there is not dust, dirt, snow and ice on the units. Dry the system components if
necessary. Take them out bags and rucksacks; remove dust and dirt from the external surfaces of the Tx
(Rx) with soft cloth.
Mechanical impacts on the unit surfaces are not allowed
. Remove dust from the
external surfaces of the charger with soft cloth. The charger must be OFF and disconnected from the
mains.
ATTENTION! Dirt on the side faces of Tx (Rx) upper cylinder reduces the system detection
probability
.
11.2.4
The system unit storage batteries are charged according to item 10.2.
11.2.5
The charger external cables state is monitored visually. Pay attention to the integrity and
technical accuracy of the mains cord and cables of the channels.
11.2.6
Lubricate rubbing surfaces and axes of the following pole details with gun lubrication (see fig.
6.2): platforms 2, bars 4, sliding bar 3, distance bars 5.
11.3
SB Replacement in Tx (Rx)
11.3.1
SB must be replaced if:
−
for Rx and RC Rx – if any Rx generates BDC reports systematically and if any RC Rx
generates “RC Rx BDC” reports systematically before the period of continuous operation is over
(see item 3.12);
−
for Tx – if any Tx fails, i.e. alarms are generated when nobody enters detection zones of the
sectors. Tx generates short audio signals.
11.3.2
SB is replaced in the following way:
-
remove bottom (position 1) (see fig. 6.1)
-
takeout SB (position 2)
-
disconnect conductors of the cord from SB clamps
-
connect contacts to the new SB (red “+”, white “-“), put SB in to the storage battery
compartment. The conductors must not be under SB. Put the bottom and fix it with screws. Charge a new
SB.
IT IS PROHIBITTED to use Rx, Tx and RC Rx without storage batteries and to connect
them to a charger.
It causes their failure.
Note.
1 Storage batteries
COSLIGHT 3-GFM-4,0 or CSB GP 645 (Tx, Rx; 3-GFM-10,0 or CSB GP 6120
(RC Rx)
are used in the system units.
2 The warranty does not cover storage batteries.
