MSR329P
|
Description
The MSR329P is an input expansion module for the modular MSR300 family to monitor the function of connected muting lamps if the system is setup for a robot cell application. One muting lamp module can be used in each MSR300 system. To use the muting module there must be at least two MSR320P input modules. The muting lamp module can be connected anywhere in the string of input modules but the terminator must be located in the left most module. The connecting ribbon cable provides power to the MSR329P as well as a check on its status. The muting lamp module is used to drive and to monitor the muting lamps only. The MSR320 input module can operate a muted cell operation without the muting lamp module present.
The MSR329P can be used for robot cell applications when the application requires a portion(s) of the inputs devices to the cell to be temporarily disabled. If for example, parts needed to be added or removed from the machine. The light curtain may need to be muted during this time to prevent the machine from stopping during this condition. Interlock switches can be used to determine the position of the robot within the cell to initiate the muting function.
When using the muting module, group three MSR330P output modules are required for the robot control or power. Group outputs 1 and 2 will still change state normally when an input changes state such as a light curtain. Output groups 1 and 2 are not required for robot cell applications but can be used to remove hazardous local voltages such as an arc welder during a muting condition.
The muting module has two main lamp modules and two spare lamp modules. If the main lamp module fails, the spare lamp module will be used. The MSR329P muting module requires an incandescent bulb operating between 30…200 mA to accurately determine the bulb status. LEDs cannot be used. Two LEDs provide the status information on all four lamps. They indicate if the bulbs are okay or if any have failed.
