Principles of Operation 1.1 Display The display module is a 2-line by 8-character LCD. Standard reading in operation is Gas Type xxx Units 1.2 Keypad and Function Configuration Relay settings and other configurable items are accessed through the keypad and menu display. The keypad is a set of 3 buttons recessed along the upper right side of the enclosure. It is not necessary to open the cover for use of the keypad. Access to the menus is password restricted. Press any key for 3 seconds to enter the menus. (See below for details) Figure 1 CTS-M5 Internal View - Features M-5 Operation And Maintenance Manual 83850-001-000 RG Aug 06, 2013 41.3 Password Factory preset default password is 0017. Password can be changed. RECORD PASSWORD IN A SECURE PLACE. If the password is lost, the unit must be returned to QEL to be reset 1.4 Output Signals Options are 4-20 milliamp or 2-10 VDC linear. Choose the option by moving the jumper on JP3. On over range concentrations the signal can exceed the range slightly. IMPORTANT: Voltage monitoring should be into a monitor with at least 50 000 ohms input impedance. Voltage monitoring is not recommended over long distances, as these signals are more susceptible to induced noise than current signals 1.5 Meter Jacks Test pads accepting standard test probes are provided on the circuit card. These are labeled SigA, SigB and Common To test milliamp signals measure: • SigA to Common shorts to internal ground. • SigA to SigB without interrupting signal to monitor To Test voltage signals measure: • SigB to Common. 1.6 Signal and Display Range It is important to distinguish between Signal Range (often called Span) and Display Range. Figure 2 Signal Configuration JP3 M-5 Operation And Maintenance Manual 83850-001-000 RG Aug 06, 2013 5 Display Range is the range of concentrations the unit is capable of displaying (which is the same concentration it will report on the digital communications). The display range varies with the gas type. Signal Range is the assignment of the 4 to 20 mA signal. Default assignment of 4 mA is zero concentration. The default setting for 20 mA varies with the gas type. The Signal range is fully adjustable within the limits imposed by the Display Range. Both the 4 mA level and the 20 mA level can be reassigned through the menu system. Please note that this adjustment does not change the measurement resolution. 1.7 Optional Relay Package Two relays are supplied; single pole double throw (SPDT; Form C) 1 Amp. Dry contacts only. Configuration allows setpoint adjustment for actuation point, dead-band, and delays, increasing or decreasing concentrations. The relay settings have the same range as the Display Range, and are independent of Signal Range. 1.8 Default Conditions Default conditions are those conditions, which occur: • During the short wait state on Power On. • In Fault status. • In the menu tree. In these situations the following conditions hold: • Signal set at 4.0 milliamps (2 Volts) • Relays set non-energized. • Digital communications report 0; no alarm status and 4 milliamp equivalent signal. 1.9 Sensing and Calibration Sensor type: Various electrochemical. 1.9.1 Calibration The sensor is strongly linear in it’s response to gas. It is therefore straightforward to calibrate. Two gases are needed for calibration: Zero gas (clean air) and an appropriate span gas. Adjustment is by one potentiometer on the circuit board. 1.9.2 Implications for Troubleshooting The microprocessor will detect various component faults and out-of-range conditions, and drop the output signal to 0.0 milliamps. When a fault is detected, both relays will be deactivated as well. However, it cannot detect simple out of calibration conditions, which can only be detected by applying a gas standard. M-5 Operation And Maintenance Manual 83850-001-000 RG Aug 06, 2013 62. Function and Configuration 2.1 Menu Structure and Use Note: While the keypad functions are available without opening the case. It is necessary to open the case to apply the calibration gases. The ‘keypad’ switches are located in the upper right side of the enclosure. See Figure 1 Page 3. Display: The display is 2 line by 8 character alphanumeric. The top line contains the feature name and the second contains the variable. Keypad: The keypad consists of three (3) pushbutton switches. S1 Scroll Up S2 Scroll Down S3 Enter/Accept Display at Turn-On: The display shows the following for about 2 seconds: QEL M-5 Vx.xx Ry Where: x.xx = the Software Version y = the Software Revision Followed for about 2 seconds by: ElectrCh Vx.xx Ry Where: ElectrCh = Electrochemical x.xx = the Sensor Algorithm Version y = the Sensor Algorithm Revision Display in Operation: The display shows GAS xxx Units Where GAS will show the target gas, and xxx is concentration of the gas. Units may be either ppm (parts per million) or %. M-5 Operation And Maintenance Manual 83850-001-000 RG Aug 06, 2013 7Note: Should the concentration equal or drop below an internal value, the unit will flash "CALIBR" on display line 2 every 8 seconds. Menu Activation: Press and hold any key for 3 seconds to enter the menu tree. Menu Scrolling: Use the scroll buttons to scroll up and down through the menu tree. Data Entry Mode: Enter the data entry mode by pressing S3 (Enter) while displaying any feature. This mode is indicated by an * (asterisk) at the right of the variable, and indicates that the variable may be changed by scrolling. Press S3 (Accept) to save result and return to menu tree. While in data entry mode, the Up and Down keys perform an automatic key repeat while the key is held in. Password: The first item on entering the menu tree is a Password request. The display is 0000, the default password is 0017. The * appears, indicating that a number can be entered and accepted. This number can be changed by the user (see below). Fault: In case of faults, the display will read FAULT and a fault code in the bottom LCD line (see below). Signal will drop to 0 milliamps. See section 3 below for more information on faults. 2.2 Configuration and Calibration Note: The user has control of all variables, including calarm settings and signal range (both 4 milliamp and 20 milliamp) assignments. It is important to note that these must be chosen carefully with regard to calibration. Zero calibration is done through a menu option, Span calibration is done though a potentiometer on the circuit card, not through the menu system, and so it is possible to perform the adjustment without the menu system; howdisabling of output actuation. 1.

Relay 1 Sub-menu Branch RELAY 1 Settings Press Enter to proceed to the Relay 1 Settings sub-menu (press down/up to skip Relay 1 Settings and go to next/previous menu item or sub-menu). 4.1 RELAY Enable Press Enter to change. “*” Indicates to use scroll buttons to toggle between Enable, Disable or Latching. Press Accept when done. Note that this disables the physical relay, but not the setpoint. Setpoint actuation status will still be transmitted on the digital communications link if queried. When the “Latching” option is selected, the relay will not de-actuate unless it is cancelled by pressing one of the keyboard buttons. The relay will only reset if the alarm situation has dissipated. Enable is the default. Press Down button to continue through Relay 1 Settings branch.
