Installation TP1MAN Issue 4_03-10 (MAN0630)23 2-Wire 4-20 mA Detector Maximum Cable Lengths To calculate the maximum cable run length from power source to the detector refer to the following example diagram and formula. Rloop = (Vcontroller — Vdetector min) / Idetector Maximum cable run length = Rloop / cable per metre resistance where: R loop = maximum working cable run resistance V controller = maximum available supply voltage at controller V detector min = minimum voltage at which the connected sensor can operate (sensor dependent, see individual sensor technical manual/data sheets) I detector = sensor maximum drawn current (sensor dependent, see individual sensor technical manual/data sheets) 1 2 31 2 3 +ve Signal+ve Signal -ve R L 1 2 33Detector Controller 100 Ohms

Operation TP1MAN Issue 4_03-10 (MAN0630)25 WA R N I N G Access to the interior of the controller, when carrying out any work, must only be conducted by trained personnel. Switch off and isolate the power supply to the controller, or obtain a hot work permit, when access is required. Take any necessary precautions to prevent false alarms. Once powered, Touchpoint 1 displays gas concentration, alarm, fault and status information on its view screen. Touchpoint 1 is controlled and configured interactively via a menu system and a set of control buttons. This chapter provides operational information about the following: • powering-up • information on the display, see page 26 • control buttons, see page 31 • menus, see page 32 • dealing with alarms, see page 33 Powering Up Touchpoint 1 is mains AC and/or DC powered. Power-up/power-down the controller using the ON/OFF switch located on the Terminal Module, as follows. 1 Access the interior of the controller. See page 12. 2 Switch on Touchpoint 1. The controller is now in normal operation. Note After switching on or off always close the access panel. On/Off Switch & Fuse Operation
Operation TP1MAN Issue 4_03-10 (MAN0630)26 Information on the Display The controller features a user interface that, during normal operation, displays gas reading information, and also system fault and information messages. It displays status and configuration information about the system via a menu options accessed and controlled via four buttons (3 are hidden) below the display, see page 31 and page 32. An audible alarm sounds whenever an abnormal event occurs, e.g. gas alarm, fault, etc. 3 LEDs below the screen indicate status information - power on (green), gas alarm (red) and fault (amber). Caution Gas events occurring at the detector while in menu mode are not reported at the controller. At switch on all display icons/text/numbers/ symbols on the display are lit for 1 second. They then show a warm-up count down from C180 (3 minutes) to C000. To skip the warm-up sequence press the channel’s Cancel button for 3 seconds. The display screen shows the gas concentration (both graphically and numerically), range, units, alarm/fault status and configuration mode. The diagram shows the display layout. The meaning of the menu icons is explained on page 32. Status Indications Typical display indications and default relay status for a particular operational state are shown in the following examples.
