– During warm-up phase.
– During maintenance.
For the current of the analog interface corresponding to the
analog signal, see 17.2.
Display example
Description
Value is over measuring range
(Over range / Upper hockey sticks)
The gas concentration is beyond the
measuring range of the sensor.
Analog interface: Measuring range
exceeded
Relays: A2 relay switches
Value is under measuring range
(Under range / Lower hockey sticks)
The gas concentration is beyond the
measuring range of the sensor.
Analog interface: Drift below zero
Relays: Fault relay switches
Fault indication
A fault has been detected.
The display toggles between Err and
the error number.
Analog interface: Fault signal
Relays: Fault relay switches
Warning indication
A warning has been detected.
The display toggles between Info and
the warning number.
Analog interface: Maintenance sig-
nal
Relays: Fault relay switches
Warm-up phase Polytron 5xx0
except Polytron 5100 EC
Analog interface: Maintenance sig-
nal
Relays: Fault relay switches
During warm-up phase 2 the fault
relay does not switch.
Warm-up phase Polytron 5100 EC
Time in minutes until warm-up is com-
plete or time in minutes until calibra-
tion is allowed.
Analog interface: Maintenance sig-
nal
Relays: Fault relay switches
During warm-up phase 2 the fault
relay does not switch.
1) For warm-up phase 1, the fault relay behavior is configurable (see
"Setting fault relay warm-up 1", page 20).
8.1.3 Ending special states
Value under/over measuring range
The display indicates that the gas concentration is beyond the
measuring range of the sensor. The indication disappears as
soon as the gas concentration is within the measuring range.
Instructions for use
|
Dräger Polytron 5000 Series
NOTICE
Sensor malfunction
Gas concentrations beyond the measuring range of the
sensor might cause sensor malfunctions.
► Check the calibration.
Polytron 5200 CAT-specific
An over range has to be acknowledged with [OK] after
verifying that the gas concentration is below 100 %LEL (e.g.
using a portable instrument).
Fault / warning indication
Faults and warnings are non-latching. If the fault or warning
condition clears, the message disappears.
To solve warning and fault conditions, display the error code
or warning message (see "Displaying error codes", page 20)
and begin troubleshooting (see "Troubleshooting", page 17).

LED and symbol indications
Symbol
LED status
– When the first alarm (pre alarm) has been triggered the
red LED flashes in single mode
– When the second alarm (main alarm) has been triggered
the red LED flashes in double mode
– When an alarm is acknowledged before the alarm
condition clears, the red LED is lit continuously to indicate
1)
the present alarm condition.
NOTICE
The alarm triggering function is only available when the
optionally integrated relay module is used.
8.3
Menu
Menu items toggle between their full name and their setting
1)
(e.g. A1 - Set - 16.9). Values and setting choices flash when
they can be edited (data entry mode).
After 15 minutes of inactivity within the menu, the instrument
times-out and returns to normal operation without accepting
any changes. At the 14 minute interval, the three unit icons
start to flash.
The instrument is designed for the magnetic wand (part
number 4544101: blue body, white logo) to be used with the
enclosure lid in place. If the enclosure lid is not in place, the
magnetic wand may activate two or more buttons at once
(cross-talk).
1) Except E108, this fault is latching.
