Option 115 - Installation in 3497Al3498ASwitching SpeedAs factory configured, the actuator has a restriction on repetitive switching. Programmingand execution of a single or multiple channel closure or open requires 40ms.However, repetitive changes of the same actuator assembly requires 1.5 sec betweencommands.For example, if a command is sent at t=O to an actuator in slot n (n = 0 to 71,the 3497A delays a subsequent command to this actuator for a minimum of 1.5seconds. This restriction does not affect other assemblies and a command can besent to an another slot immediately after the command to the slot n actuator.If required for proper load operation, card operation can be changed to 25 operationslsecond(40 msec delay) by removing jumper JMP 9 on the actuator card. SeeFigure 137 for JMP 9 location. This change will allow high speed switching for allchannels on the assembly.Artisan Technology Group - Quality Instrumentation ...
