3 . CHANNEL GAS DATA & ALARMS A general form of item numbers is shown below. The "x" shown in each item number should be replaced by the channel number ( - ). This sequence covers item numbers 0 - and For channels 0 - these item numbers are 00 - & For channels & & channels & 00 - x0 x0 4x0 5x0 Channel Selection OFF on 0 - on x x 4x 5x CPC Device No 0 disabled - 47 as channel No. x7 x7 4x7 5x7 Mode 0 strt rdy C.E.FL sh.dn C.C.FL Unknown Warm up Ready CPC equipment fault Shutdown CPC communications fault x6 x6 4x6 5x6 CPC status strt run Lo.AL SP.AL Warm up Ok Low level alarm Critical alarm x x 4x 5x Gas Concentration (0ppm) x4 x4 4x4 5x4 Average Gas Concentration (0ppm) x5 x5 4x5 5x5 x8 x8 4x8 5x8 Period over which averages taken CPC Alarm delay (mins) 00:0-04:00 00:0 x x 4x 5x Network command status run sh.dn Run Shutdown 6x0 7x0 8x0 x0 Leak Alarm level (0ppm) 6x 7x 8x x Spill alarm level (0ppm) 6x5 7x5 8x5 x5 CPC Warm up state run Strt Run Warmup JTL Systems Ltd Doc No wpd Issue Aug

5 8. RESTORE FACTORY DEFAULT DATA Set default values Set default values Write to NVRAM without delay. RESTORE PARAMETERS FROM NETWORK To restore the data from the network first set appropriate unit number on item. Then check item 65 to see if this facility is available on the network. The information on item 65 is received from a network broadcast every few minutes. If the restore parameter facility is available and operational then item 65 will be set to a non zero number e.g.. To request restore parameters set item 64 to 4. Item 6 displays the parameter restore progress. When all parameters are downloaded item 64 is cleared to Master database port 0-4 Not in use NC port no 64 Set restore parameters from network 4 Request restore 6 Parameter restore progress rdy dnl.r din.p dnl.c FAIL 5 Requested template 0 - Restore function possible Restore requested Restore in progress Restore complete Restore fault As commissioned Template number 0-0 SYSTEM ALARMS Note: Alarms are only shown when item is disabled. For channel alarms see channel data (section ) items x6 & x6 where x is the channel number. 80 Group alarm 8-88 (see display data) 88 Unit number corrupted/not set 0-55 CLr Un.CF No alarms Check 8-88 JTL Systems Ltd Doc No wpd Issue Aug

6 . DIAGNOSTIC & TEST FUNCTIONS 6 Jnet communications speed kilo baud rate 7 wire communications HALF wire 67 Latest unit no polled on zone 7 Latest polling interval This time shows the polling interval between the last two successful network awake messages to this unit. min:sec 74 Time since last awake message min:sec 75 Network receive timer Each time a message is read correctly the timer is set to 0 it counts down. If the timer reaches 0 then the communications module is reset. 76 Network receive bad character counter. The counter counts down from a preset number. When the counter reaches 0 the communications module is reset. seconds (counts down to 0) (counts down to 0) 8 Bitswitch setting Not used Test digital display CLr SEt Not active Test active 0-0 Processor alarms (-7) (see display data) 0-55 No alarms Check -7 Static RAM fault CLr ra.ft Program/counter fault CLr PC.Ft Stack pointer fault CLr SP.Ft 4 Background loop fault CLr bl.ft 5 PROM checksum fault CLr Pr.Ft 6 NVRAM fault CLr n.ft 7 Instruction TRAP fault CLr tp.ft JTL Systems Ltd Doc No wpd Issue Aug
