The following parameters can be set: 
 

Configure Test Modes Settings 

 

Temporary Overspeed Trip: 

Overspeed setpoint setting for overspeed tests with actual turbine or 

equipment speed signal, used while the Temporary Overspeed Trip Test is active. Frequency 
equivalent must not exceed 32000 Hz or a Configuration Error will occur. Valid values: 0 - 80000 
RPM. 

 

Temporary Overspeed Trip Timeout: 

Sets the time allowed to raise the actual turbine or 

equipment speed above the temporary overspeed setpoint in order to test the trip action. If the 
overspeed setpoint is not exceeded within this time span, the overspeed test is aborted. Valid 
values: 0 - 1800 seconds. 

 

Simulated Speed Timeout: 

Sets the maximum time allowed during the Manual Simulated Speed 

Test. If the overspeed setpoint is not exceeded within this time span, the overspeed test is aborted. 
Valid values: 0 - 1800 seconds. 

 

Test Mode Permissive:

 Sets the desired permissive level. This permissive function is used to 

prevent a test routine from running when another module is tripped, in alarm, or in a test mode. The 
permission applies to the Auto or Manual Simulated Speed Tests. It does not apply to the Temporary 
Overspeed Test or Auto-Sequence Test. Valid values: 

o

 

No Inter-module Permissive:

 Test will run even if another module is tripped, in alarm, or in a 

test mode.

 

o

 

Module Not Tripped:

 Test will only run if other modules are not tripped and not in a test mode. 

o

 

Module Not In Alarm:

 Test will only run if other modules are not tripped, not in alarm, and not in 

a test mode. 

 
The test active indications are automatically connected internally to the alarm latch. 
 

Auto-Sequence Test 

This page is used to configure the Auto-Sequence Test mode. Note that Module A is the first module 
tested in this function, next is Module B, then finally Module C. The auto sequence test mode requires all 
modules to be not tripped, not in alarm and not running a test. Since Module A initiates the test sequence, 
the test can only be configured on Module A. 
 
The following parameters can be set on Module A: 
 

Auto-Sequence Test Settings

 

 

Periodic Test Timer Enabled: 

This setting is used to enable the Auto-Sequence Test function to be 

performed on a periodic basis. When set to “Yes” the Auto-Sequence Test routine will be performed 
periodically based on the Periodic Test Timer interval setting. When enabled, this timer starts at 
power-up.

 

When set to “No”, the periodic test is not run, however the auto-sequence test can still be 

manually initiated from the front panel.

 

Valid values: Yes or No.

 

 

Periodic Test Timer Interval: 

If timer is enabled, this setting is used to set the time interval/period 

between when an Auto-Sequence Test function is performed. Valid values: 1 - 999 days. 

 

Operator can disable test:

 Set to “Yes” to permit test intervention as well as prevent the test from 

starting automatically. Test disable command options are available from the front panel. When set to 
“No”, the test cannot be manually stopped. This setting is used to allow temporary disable of the 
periodic execution of the Auto-Sequence Test. Valid values: Yes or No.

 

 
Indications for Auto Sequence Test Active and Auto Sequence Timeout are automatically connected 
internally to the alarm latch.
