211.6.8 Master/Slave SystemNB. The total cable length of the network (using the cable recommended by V.H.C.L. – Our partnumber 8040251) is 500 m and it should be assumed that there is 1 m of cable in each unit of the“system” (including the “master”).For larger duties, VAPANET “Electrode boiler” units can be interconnected and arranged to operate from one proportional signal as aMaster/Slave system. The system allows up to 10 cylinders to be linked in this way. The slave units will all be “on / off” units. The masterunit, to which the proportional signal is connected, can be “on / off” but will preferably be a “proportional” unit.To “configure” a system, ensure that the control signal is zero [disconnect the control signal, or switch the units off at the front panel switch].Press and hold the service pin on the master control PCB, until the user LED’s flash amber, release and check that the LEDs flashred/amber/green, if not repeat the procedure. Then press the service pin (network button) on each of the slave control PCB’s in the orderthat they are required to operate, the slave user LED1 will flash Green/amber until it is configured, once the light goes out [or flashesred/off], proceed to the next slave. If units of different capacity are used, ensure that the master is equal to or greater than the capacity ofthe slaves, and that the largest capacity slaves come on before the smaller capacity units]. Once this process is complete, confirm the factby pressing the service pin on the master PCB until user LED2 goes green [this step is not necessary if all nine slave cylinders areconfigured].xxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxEsc VapacJ2Vapac part no 1150631CR1Net J1Vapac PART No. 115063016CR5 1NetCR7J6J5 CR6 16610CR316J1J2J31F2CR11F1 CR2J418CR4116Vapac PART No. 115063016CR6 1NetCR7J6CR5 16610CR316J1J2J31F2CR11F1 CR2J418CR4116J240K 48KJ5V 0VCR4CR12CR2A B A BCustomers terminals within unitlocated on low voltage rail"Slave" unit with display.PCB for "Master" orcurrent only.signal is mALink if controlJ1 see section 1.9.1Network Coms,LEDconfigurationresistorUCP1NetworkButton9/24V ac SupplyTerminal 543 - Unit Alarm (normally closed)Terminal 544 - Unit Alarm (normally open)J1 see section 1.9.1Not required forNot required forJ1 see section 1.9.1PCB for "Slave 1" to"Slave 9" units.slave unit.slave unit.Terminal 542 - Unit Alarm (Common)Terminal 545 - Unit Run (Common)Terminal 546 - Unit Run (normally closed)Terminal 547 - Unit Run (normally open)CR6 gives the following remote indicationsas Volt-free contacts:Remote IndicationsConnection toDisplay if fittedcomponents.other networkslave units 2 to 9 orNetwork Expansion toconfigurationUCP1resistorFRONT VIEW OF 1150630 BOARDon the master unit.plugged into CR41150634 which isconfiguration boardresistor is fitted onUCP1 configurationwith a display thenIf unit is not fittedDisplay & Keypad(Optional)Network LEDNetwork ButtonUSER LED 1USER LED 2 |
