Functional Test - Elektrotechnik Schabus GX-HS Notice D'utilisation

Sensor connection configuration
Observe the colour coding of the sensor cable (see connection diagram below).
Relay connection configuration
When connecting additional devices to the potential-free relay, please note that the switching
capacity may not be exceeded.
► Relay status in monitoring mode:
The relay is „energized" (make contact closed/break contact open)
► Relay status in alarm mode:
The relay „decreases" (make contact open/ break contact closed)
Storage function adjustments
Two differing output messages can be defined for the sensor input:
► Alarm message with storage function (wire jumper at terminals 17-18): The alarm
stays on and the relay is switched on, until the message is turned off again by pushing
a button.
► Alarm message without storage function (no wire jumper): The alarm continues and/
or the relays are connected until the detected gas has volatilised.
Buzzer connection (optional)
A buzzer can optionally be connected to the terminals 14 and 15. Connection value: 9–15
V/max. 50 mA
START-UP
When connecting grid voltage to the device, both LEDs (Sensor and Power) light up. The
sensor of the monitoring system requires a warm-up time of max. five minutes until it is
functional. Then only the Power light is illuminated in green and the GAS ALARM GX-HS is
operational. Please note: The warm-up time will be restarted even in the event of a power
failure.
ATTENTION: Due to different transport conditions (long storage/moisture), an alarm may be
triggered directly after warm-up time (Sensor LED blinks red). Disconnect the device from
the grid for a short time and restart the warm-up time. This process may have to be repeated
up to three times.

FUNCTIONAL TEST

After the GX-HS and the sensors have been set up, a functional test must be carried out.
For the functional test of the sensor, please note the operating instructions of the sensor
you are using!
ATTENTION: The device only triggers an alarm and the LED Sensor flashes red if the sensor
has detected an elevated gas concentration for longer than 20 seconds. The Power LED is
no longer green. Once the gas has volatised, the device switches to monitoring mode. For
the save function, press the <RESET> button, thereby clearing the alarm. The device swit-
ches back to the monitoring mode.
