Page 6: The System Mx62
1. The System MX62 MX62 is a statio nary control system and evaluator to be used in combination with a va- riety of transmitters for continuous detection of combustible gases, toxic gases and oxy- gen. Main features are high reliability as well as remarkable flexibility. This flexibility refers to all areas, such as free programmability and placing of relays and analogue outputs as well as optional installation in wall- mounted housings, 19”-racks or control panels. -
Page 7: Description Of Modules
2.1. Description of Modules 2.1.1. Controller Module (CM) The Controller Module is the central control unit of the system for all 64 channels of maximum configuration. Two synchronously working 16-bit micro controllers redun- dantly process the measured values of the Analogue Input Modules. Via a redundant bus, the status of the relays and the analogue output signals are transmitted to the Re- lay and Analogue Output Modules respectively. -

2.1.5. Loop Module (LOOPM) The Loop Module for MX62 offers the possibility to build a network of digital transmit- ters or to record measured values of any standard 4-20 mA transmitter by means of the Analogue Input Modules connected to a Loop Module. -
Page 9: Analogue Output Module (Aam)
2.1.7. LCD Module The system MX62 can be equipped with a graphic LCD display (240 x 128 pixels) showing, for example, information on measuring points, all relevant system parame- ters as well as system events and histograms. The LCD Module is provided with an in- tegrated data logger with a storage capacity of up to 64 MB. -
Page 10: Mimic Module
It is possible to copy the LED Modules by using MIMIC Modules. The MIMIC Module has to be connected to the “display bus” of the system MX62. Each MIMIC Module copies exactly one LED Module. It is possible to connect a fur- ther LED Module to the MIMIC Module or to copy the primary LED Module by using the open collector outputs of the MIMIC Modules. -
Page 11: Description Of Redundancy

Page 14: Normal Operation
(see chapter 4) Printer: 3.2.2. Alarms The system MX62 has three free adjustable alarm levels within the measuring range of ® 4-20 mA. The software ConfigPro allows, for example, adjusting of alarm levels, latching of alarms or setting of alarm thresholds for mean values within a specified time. -
Page 15: Channel Malfunction
Printer: ATTENTION! The gas detection system MX62 differentiates the faults of a specific channel from those of the complete system (chapter 3.6). If channel malfunctions have to trigger an external measure automatically, the signals in configuration need to be allocated to one or sev- eral relay outputs. -

LEL or LEL, > end scale value, message: over scale, display of measured value is frozen Printer: Case B: Threshold for over scale is below the end scale value MX62 will react as if an alarm has been signaled (see 3.2.2). -
Page 17: Resetting Of Alarm Signals
3.2.7. Resetting of Alarm Signals There are two different types of resetting: • Resetting of Audible Alarm Signals : Relays can be configured to be reset. In general, these should, however, exclusively be employed for the triggering of buzzers, sirens and other audible alarm indicators. -
Page 18: Start-Up Mode
3.3. Start-up Mode Upon start-up or directly after voltage cut-off, alarm signals are blocked for 1 to 10 ® minutes (setting by software ConfigPro ). After the start-up mode, the system auto- matically enters into the operating status. Ü As many transmitters signal undefined values after start-up, this mode eliminates any false alarms. -
Page 19: Alarm Suspension
3.4.1. Alarm Suspension Switch Position 1 The suspension of alarms prevents that relays which are related to alarms, faults, over- or under scale are not taken into account and are consequently not triggered.

Safety Integrity Levels. Since visual indications are not integrated into the chain of safety control and will there- fore not have any impact on the chain of safety control of MX62, these will not be taken into account for configuration requirements. - Page 53 When configuring MX62, please observe that each connected transmitter is monitored for any short circuit or interruption of power supply which will then trigger a fault alarm. Note: If two or more transmitters are to monitor the same area, it will have to be made sure that the transmitters will not stop operating for same reason such as poisoning of the sensor or power failure.
