25.2 My Rack Does Not Use a SAM Module
VC-8000 monitor modules can operate without a SAM installed in the rack. Operation without a SAM
provides a cost-effective solution when the monitors do not need to function as a system, such as
when monitoring many small machines.
The following have restricted functions when there is no SAM in the rack.
Function Behaviour without SAM
Configuration
Software
Rack (system) communications are not supported. To configure any module, you
must connect to the USB port on that module.
Each module must be configured independently. When you ‘Get’ a configuration,
you will only see one module (the module the USB cable is connected to). When
you ‘Send’ a configuration you will only change one module and you will have a
configuration file for each module.
Relay logic is restricted to the channels in that module. You cannot include
channels from other modules in your relay logic.
Event List
Each monitor module records only the events generated by that module, and its
event list is cleared when the module is rebooted.
Events are recorded in sequence but there is no time-stamp.
The monitors record the results of system level actions, such as channels leaving
alarm on a reset, rather than the reset event itself.
Maintenance Software
The Maintenance Software can only connect to, and display information from, one
module at a time.
It will not be possible to see RCM conditions and statuses (power OK, rack inhibit,
rack trip multiply, etc.)
25.3 Resetting Held Values
Peak Speed, Peak Reverse Speed, Number of Reverse Rotations values are held until reset. VC-
8000 Maintenance software is required to reset the values back to zero; navigate to the Detail More
View and click the Reset Held Values button.
25.4 Contacts View (Discrete Input Channels)
UMM Discrete Input channels can perform Trip Multiply, Inhibit, and
Bypass functions for groups of channels within the rack. The discrete
contacts on the RCM only perform these functions for the entire rack.
To configure Discrete Contact channels:
• Set the channel type as: Discrete Input.
• Select the transducer (input signal) type. Typically, this will be set to: Dry Contact.
• Configure Asset Level 1 (Machine Train) group names.
• Set parameters in the Contacts View.
25.4.1 Contact Function
The available contact (control) functions are:
• Bypass: places all channels in the group into Channel Bypass.
• Inhibit: places all channels in the group into Alarm Inhibit
• Trip Multiply: places all channel in the group into Trip Multiply.
