WARNING
Risk of explosion
To reduce the risk of ignition of a flammable or potentially explosive atmosphere,
observe the following:
► Do not open the gas detector in explosion-hazard areas.
► Only the battery types specified in the technical data must be used.
► Do not charge or replace the battery in potentially explosive atmospheres or in
explosion-hazard areas.
► Check that the fastening screw of the battery pack is secure before use.
NOTICE
Damage to the gas detector
The power pack for the X-am 2500/5000/5100/5600 gas detectors (order
no. 8318704) must not be used for the X-am 2800, as the seal cannot ensure the IP
protection for the X-am 2800 and was not approved together with the X-am 2800.
► Only use the battery pack (order no. 3703887) with visible part number 3703880
as power pack.
1. Switch off the gas detector.
2. Undo the screw on the power pack.
3. Remove and replace the NiMH power pack T4 (type HBT 0010).
4. Insert the power pack into the gas detector and tighten the screw, the gas
detector switches on automatically.
6.11 Exchanging, adding or removing a sensor
In gas detector X-am 2800, only the permitted sensors may be registered.
X-am 5800: These gas detectors are delivered with the sensor damper and
sensor placeholder installed for CatEx and IR. If a PID sensor is to be installed, the
PID X-am 5800 sensor damper set (order no. 3703864) or alternatively the PID neo
upgrade set (includes damper and PID HC neo sensor, order no. 3703907) must be
purchased.
When a sensor is removed from the gas detector and not replaced, the
corresponding sensor placeholder (CatEx/IR or PID or EC (electrochemical
sensor)) must be inserted in its place.
Equipment:
– Torx T6 screwdriver for the housing
– Torx T8 screwdriver or Allen key (2 mm) for the power pack
– Special tool for removing EC sensors (Order no. R21402)
– New sensor
– Sensor damper, if required
– Sensor placeholder, if required
