User Guide | Danfoss Gas Detection - Controller unit and Expansion module
1 |
The Danfoss gas detection controller unit is |
Intended use |
controlling one or multiple gas detectors, for |
|
monitoring, detection and warning of toxic and |
|
flammable gases and vapours in the ambient |
|
air.. The controller unit meets the requirements |
|
according to EN 378 and the guidelines “Safety |
|
requirements for ammonia (NH3) refrigeration |
|
systems”.. |
The intended sites are all areas being directly connected to the public low voltage supply, e..g.. residential, commercial and industrial ranges as well as small enterprises (according to EN 5502).. The controller unit may only be used in ambient conditions as specified in the technical data..
The controller unit must not be used in potentially explosive atmospheres..
2 |
The controller unit is a warning and control unit |
Description |
for the continuous monitoring of different toxic |
|
or flammable gases and vapours as well as of |
|
HFC and HFO refrigerants.. The controller unit is |
|
suitable for the connection of up to 96 digital |
|
sensors via the 2-wire bus.. Up to 32 analog |
|
inputs for the connection of sensors with 4 to |
|
20 mA signal interface are available in addition.. |
|
The controller unit can be employed as pure |
|
analog controller, as analog/digital or as digital |
|
controller.. The total number of connected |
|
sensors, however, may not exceed 128 sensors.. |
|
Up to four programmable alarm thresholds are |
|
available for each sensor.. For binary transmission |
|
of the alarms there are up to 32 relays with |
|
potential-free change-over contact and up to 96 |
|
signal relays.. |
Comfortable and easy operation of the controller unit is done via the logical menu structure..
A number of integrated parameters enables the realisation of various requirements in the gas measuring technique.. Configuration is menu-driven via the keypad.. For fast and easy configuration, you can use the PC based
configuration software, included in the PC tool..
Prior to commissioning please consider the guidelines for wiring and commissioning of the hardware..
2.1 |
In normal mode, the gas concentrations |
Normal Mode |
of the active sensors are continuously |
|
polled and displayed at the LC display in a |
|
scrolling way.. In addition, the controller unit |
|
continuously monitors itself, its outputs and |
|
the communication to all active sensors and |
|
modules.. |
2.2 |
If the gas concentration reaches or exceeds |
Alarm Mode |
the programmed alarm threshold, the alarm is |
|
started, the assigned alarm relay is activated and |
|
the alarm LED (light red for alarm 1, dark red for |
|
alarm 2 + n) starts to flash.. The set alarm can be |
|
read from the menu Alarm Status.. |
|
When the gas concentration falls below the |
|
alarm threshold and the set hysteresis, the alarm |
|
is automatically reset.. In latching mode, the |
|
alarm must be reset manually directly at the |
|
alarm triggering device after falling below the |
|
threshold.. |
This function is obligatory for flammable gases detected by catalytic bead sensors generating a falling signal at too high gas concentrations..
2.3 |
In the special status mode there are delayed |
Special Status Mode |
measurements for the operation side, but no |
|
alarm evaluation.. The special status is indicated |
|
on the display and it always activates the fault |
|
relay.. |
|
The controller unit adopts the special status |
|
when: |
|
- faults of one or more active devices occur, |
|
- the operation starts up after return of voltage |
|
(power on), |
|
- the service mode is activated by the user, |
|
- the user reads or changes parameters, |
|
- an alarm or signal relay is manually overridden |
|
in the alarm status menu or via digital inputs.. |

2.3.1 |
If the controller unit detects an incorrect |
Fault Mode |
communication of an active sensor or module, or |
|
if an analog signal is outside the admissible range |
|
(< 3..0 mA > 21..2 mA), or if there are internal |
|
function errors coming from the self-control |
|
modules incl.. watchdog and voltage control, the |
|
assigned fault relay is set and the error LED starts |
|
to flash.. |
The error is displayed in the menu Error Status in clear text.. After removal of the cause, the error message must be acknowledged manually in the menu Error Status..
2.3.2
Restart Mode (Warm-up Operation)
Gas detection sensors need a running-in period, until the chemical process of the sensor reaches stable conditions.. During this running-in period the sensor signal can lead to an unwanted release of a pseudo alarm..
Depending on the connected sensor types, the longest warm-up time must be entered as poweron time in the controller..
This power-on time is started at the controller unit after switching on the power supply and/or after the return of voltage..
While this time is running out, the gas controller unit does not display any values and does not activate any alarms; the controller system is not yet ready for use..
The power-on status occurs on the first line of the starting menu..
2.3.3 |
This operation mode includes commissioning, |
Service Mode |
calibration, testing, repair and decommissioning.. |
|
The service mode can be enabled for a single |
|
sensor, for a group of sensors as well as for the |
|
complete system.. In active service mode pending |
|
alarms for the concerned devices are held, but |
|
new alarms are suppressed.. |
2.3.4 |
The supply voltage is monitored in all modes.. |
UPS Functionality |
When reaching the battery voltage in the power |
|
pack, the UPS function of the controller unit is |
|
enabled and the connected battery is charged.. |
|
If the power fails, the battery voltage drops down |
|
and generates the power failure message.. |
|
At empty battery voltage, the battery is |
|
separated from the circuit (function of deep |
|
discharge protection).. |
When the power is restored, there will be an automatic return to the charging mode..
No settings and therefore no parameters are required for the UPS functionality..

4.3 |
According to the regulations of national and |
Code Levels |
international standards for gas warning systems, |
|
all inputs and changes are protected by a |
|
four-digit numeric code (= password) against |
|
unauthorised intervention.. The menu windows of |
|
status messages and measuring values are visible |
|
without entering a code.. |
|
The release of a code level is cancelled if no |
|
button is pushed within 15 minutes.. |
|
The code levels are classified in order of priority: |
|
Priority 1 has top priority.. |
|
Priority 1: (code 5468, not changeable) |
|
Code level priority 1 is intended for the service |
|
technician of the installer to change parameters |
|
and set-points.. This password allows working on |
|
all settings.. For opening the parameter menus |
|
you must first activate the service mode after |
|
code release.. |
|
Priority 2: (code 4009, not changeable) |
|
With code level 2, it is possible to lock / unlock |
|
transmitters temporarily.. This password is only |
|
given to the end user by the installer in problem |
|
situations.. In order to lock / unlock the sensors |
|
you must first activate the service mode after |
|
code release.. |
Priority 3: (code 4321, is settable in the maintenance information menu)
It is only intended to update the maintenance date.. Normally the code is only known by the service technician who has last changed it since it can be changed individually via priority 1..
Priority 4: (password 1234) (code not changeable)
Code level priority 4 allows the operator:
-to acknowledge faults,
-to set date and time,
-to configure and to operate the data logger option, after activation of the operation mode “Service Mode”:
-to read all parameters,
-to manually operate test function of the alarm relays (functional test of the connected units),
-tomanuallyoperatetestfunctionoftheanalog outputs (functional test of the connected units). .
