The detector shall be installed with the cable gland pointing downwards. For explosive gas detectors only, any tilt of more than 45° from the vertical will lead to an inaccurate measurement. OLCT10N Manual... -
Page 9: Connection
Connection RS485 transmission There are two cable entries on the OLCT10N, one entry is for the input signal and one is for the output signal – this is used for digitally connecting multiple transmitters on a single line to the MX43 Controller. -

Inspection or calibration is then recommended. Operation under low oxygen levels If an electrochemical detector sensor is used in an atmosphere comprising less than 1% oxygen for over one hour, the measurement may be an underestimate. OLCT10N Manual... -
Page 13: Chapter 3 | Maintenance
Frequency of maintenance Gas detectors are safety devices. OLDHAM recommends the regular testing of fixed gas detection installations. This type of test consists of injecting the standard gas into the detector at a sufficient concentration to activate the pre-set alarms. It is to be understood that this test is in no way a replacement for a detector calibration. -
Page 14: Automatic Calibration
The OLCT10N can be calibrated either : Manually Or automatically The manual calibration have to be made only after each sensor or detector replacement. A manual calibration has to be followed by an automatic calibration. Please find below the different calibration gas concentrations. - Page 15 Magnetic calibration cap ON Cal ON LED detector status Cal OFF Magnetic calibration OFF Start sensor stabilization Power down if OK [ 1 mn ] Blinking if fault Power down if OK Normal Blinking if fault Cal ON Calibration beginning Cal OFF GREEN Réel...

Page 17: Sensor Replacement
Sensor replacement Sensors should be replaced as a part of regular preventative maintenance or following a failed calibration test. After a sensor replacement, both manual and automatic calibrations have to be conducted To change the sensor: 1. Remove the detector cover 2. -
