Page 7: Overview
1.1 OVERVIEW Model PT2008 series “Wireless” monitor & controller is designed to monitor and display data from remote mounted Ultra 1000 Series (wireless) sensors (toxic and Combustibles). Controller can communicate with up to 24 detectors on the wireless network. The controller features a large LCD display, 6 fully programmable alarm relay contacts, and a communication or sensor fault relay. -
Page 8: Data Display
1.2 DATA DISPLAY PT2008 Controller displays sensor location tags ( or default channel numbers) and the sensor readings. For controller configured for more than 8 wireless detectors , data is displayed eight channels at a time. Each screen displays data for 10 seconds and then display is switched for next 8 channels and so on. -

Page 15: Startup
3.2.2 Alarms PT2008 monitor is equipped with four (4) alarm relay contacts. The monitor activates the alarm relays when any of the sensors exceeds the programmed alarm set point. Also, the LEDs on the front panel will also light up for visual alarm indication. -
Page 16: Alarm Reset
3.2.3 Alarm Reset Once the gas concentration has dropped below the alarm setpoint the relay will deactivate itself. However, this will occur only if the relay is configured as non-latching (NL). If the relay is configured latching then it must be deactivated manually. To deactivate the latching alarm simply press and hold RESET switch on the front panel for few seconds. -

1. Start the Hyper Terminal program on the laptop computer as explained in the next section. 2. Connect RS232 port on PT2008 to Serial Comm Port on laptop using standard DB9 Male-Female RS232 cable. 3. From main configuration menu select “Program Location Tags” option and the press ENTER key. - Page 22 • PT2008 prompts with message that tag names have been saved. • Press “4” key on the keyboard to return to normal operation. PT2008 Controller will now display the new sensor location tags in the first column of the LC display.

Page 24: Network / Zone Id
Network / Zone ID is used to avoid the cross talk between multiple sensors and controllers. Cross talk happens if multiple PT2008 Controllers are used within short distance to each other and sensors. A controller and all the associated sensors must have the same network ID in order to communicate properly. -
Page 25: Communication To Plc
Modbus RTU is a standard protocol for communication between a PLC / Controller and slave devices. This section briefly explains the communication with PT2008 Controller through Modbus RTU protocol. Only the PLC / Controller can make requests to read the contents of the data registers in the controller. - Page 26 400001 thru 400010 - System Status and misc. housekeeping registers 400001 System “Heart Beat” register Unsigned 16 bit integer value This register is increment once every second (approximately) The maximum value is 65535 after which it rolls over to 0 400002 Inter-processor communication failure Integer value 0 or 1...

Page 27: Modbus Register List / Map
MODBUS Register List Each sensor has 4 MODBUS register block. Register for the sensor are sequential. First register is for current gas reading, second register has sensor status and diagnostics bit map, third is register holding data for the battery voltage. Fourth register is used internally and should not be read by the user’s PLC . - Page 28 Status Bit Map Register This is a 16 bit integer register. Each bit / byte is used for sensor status and diagnostic information. The MSByte ( Most Significant 8 bits) of this register contains the sensor type code as listed in table 2. The LSByte ( Least Significant 8 bits) defines the status of sensor as shown in the data frame below.
