- Smartphone with CRLDS App Installed (optional)
TEST PROCEDURE
STEP 1:
Attach the provided calibration adapter to the sensor.
STEP 2:
Connect to the CRLDS via Bluetooth and prepare to monitor the sensor while
gas is flowing.
-
Download and install Copeland CRLDS app from the App Store® or Google Play Store.
-
Activate Bluetooth® on the CRLDS sensor by touching the red magnetic wand to the magnetic switch on top of the enclosure for 5 seconds continuously.
-
Once Bluetooth® is activated, the green LED will change from solid green to blinking green.
-
Open the CRLDS app, select Technician and login with password 2222.
-
Select on the CRLDS serial number in the device list to connect.
-
From the home tab, select the Parameters button.
-
Select the Output Type 4-20mA, and hit back to save. Change the corresponding zone in the MZLD iPro to be 4-20mA for the analog input.
STEP 3:
According to EN 14624:2020* in “12.7 Response time” is stated that the
response time of the detector must be 30 sec (seconds) or less at a
concentration of 1.6 times the preset value.
Choose the gas sensor accordingly.
Note that in cases where semi-conductive sensors are tested, the test gas
must be balanced with air.
- Based on EN 378:2016, 9.3.1
STEP 4:
Use the gas regulator with constant flow of 0.5 L /min.
Note that in case of ammonia sensors, the stainless steel regulator must
be used.
STEP 5:
In cases where semi-conductor sensors are tested, moisten the air humidifier
with tap water.
STEP 6:
Control if the alarm indication starts within 30 seconds from the start of the
gas exposure:
LED indication: Visual inspection
Relay indication:
Sound (relays clicking)
Electrical continuity test on relay terminals
