When the Program Mode is exited, the control automatically performs a
completeness check on the configured program to assure that required program blocks have values loaded into them. This check cannot determine if the values entered are realistic, but it makes sure that values have been loaded into
required parameters. If any errors are found in the program, the ‘Config ERROR– Press PRGM’ display will appear along with the programming error(s)
discovered. If there is more than one error discovered, they can be displayed by pressing the down arrow key. This key will scroll through all the error messages and allow you to determine their cause(s).
The configuration error message alerts you that a programming change is required before the configured program can operate the turbine. You must re- enter the Program Mode and fix the problem before the control will allow the turbine to run. The completeness check will continue to fail until the control is satisfied that the configured program is complete.
This section of the manual identifies the various configuration error messages that may appear and explains the meaning of the error.
Start / Speed Program Errors
No Start Mode Selected—RUN was selected but no start mode was selected in the Program mode. One of the three start modes must be selected in the Program mode under the Start Block.
Speed > 15000 Hz—The maximum speed input is 15000 hertz. This is a limitation of the 505E’s hardware / speed sensing circuitry. The frequency input of the speed sensor must be less than this value. The gear the speed sensor is mounted on may need to be changed to one with less teeth, this will decrease the frequency seen by the speed probes.
Spd #1 Fld < Freq Range—The failed speed setting for speed input #1 is below the minimum allowed setting. The minimum allowed setting is calculated as follows: (Overspeed Test Limit) * (0.0204).
Spd #2 Fld < Freq Range—The failed speed setting for speed input #2 is below the minimum allowed setting. The minimum allowed setting is calculated as follows: (Overspeed Test Limit) * (0.0204).
Critical Speed Program Errors
Crit Rate < Slow Rate—The acceleration rate (rpm/second) through the critical speed avoidance band must be faster than the normal speed setpoint rate. Crit Spd Err / No Idle—A critical speed avoidance band was programmed but
neither idle/rated or auto start sequence was programmed. To use the critical speed avoidance logic one of these functions that uses an idle speed must be programmed.
Lo Idle set in Critical—Either the idle speed setpoint (when using idle/rated) or the low idle setpoint (when using the auto start sequence) was programmed within a critical speed avoidance band.
Hi Idle set in Critical—The hi idle speed setpoint (when using the auto start sequence) was programmed within a critical speed avoidance band. Critical Band < Idle—The critical speed avoidance band min is below the min
speed setpoint (idle or low idle).
Idle Program Errors
Idle Setpt > Min Gov—The Idle Speed setpoint was programmed at a higher speed than the minimum governor speed setpoint.
Rated Speed > Max Gov—The Rated Speed setpoint was programmed at a higher speed than the maximum governor speed setpoint.
Generator Program Errors
KW Max Load > KW Input—The KW Max Load setting was programmed at a higher value than the maximum KW input (KW input at 20 mA).
No Utility Brkr Config—The unit is programmed for a generator application but no utility tie breaker contact input was programmed. This is a requirement. No Gen Brkr Config—The unit is programmed for a generator application but no
utility tie breaker contact input was programmed. This is a requirement. No Freq Arm/Dsarm Prgmd—The frequency arm/disarm function was
programmed but no means of arming or disarming were programmed. Either a function key or a contact input must be programmed to arm/disarm
frequency control if you wish to use the frequency arm/disarm function. Sync & Sync/Ld Shr Pgmd—Both the synchronizing analog input and the
Steam Map Prgm Error
Steam Map Prgm Error—The map coordinates have been entered incorrectly. The calculations for power and flow in the control are wrong. Entries for points A, B, and C must be so the following equation is not true.
(HPa-HPc) (Sb-Sc) > (HPb-HPc) (Sa-Sc) [for extraction or extr/adm] or
(HPc-HPb) (Sc-Sb) < (HPb-HPa) (Sc-Sa) [for admission only units] Where: HPa = Flow at Point A
HPb = Flow at Point B HPc = Flow at Point C Sa = Power at Point A Sb = Power at Point B Sc = Power at Point C
In addition, the relative levels of HPa, HPb, HPc, Sa, Sb, and Sc must be correct (refer to Program mode worksheets).
Contact Input Program Errors
Two Identical Contacts—Two contact inputs were programmed for the same function.
Contact #xx Program Err—The specified contact input was programmed for a function that is not also programmed to be used. Either the contact input was mis-programmed or the function required is mis-programmed. For example, contact input #1 is programmed for Remote Cascade Setpoint Enable but Remote Cascade Setpoint was not programmed under the Cascade Program Block.
Analog Input Program Errors
Two Identical Analogs—Two analog inputs were programmed for the same function.
Analog #x Program Err—The specified analog input was programmed for a function that is not also programmed to be used. Either the analog input was mis-programmed or the function required is mis-programmed. For example, analog input #1 is programmed for Remote Cascade Setpoint but Remote Cascade Setpoint was not programmed under the Cascade Program Block. No Rmt Speed Input Prgm—The remote speed setpoint control function was
programmed but no remote speed setpoint analog input was configured. No KW Analog Input—Either the auxiliary control function was programmed to
use the kW input or kW droop was programmed but no kW analog input was configured.
No Sync Analog Input—A synchronizing contact input was programmed but no synchronizing analog input was configured.
No Ld Share Analog In—A load share or sync/ load share contact input was programmed but no load share analog input was configured.
No Cascade Analog Input—The cascade control function was programmed but no cascade analog input was configured.
No Rmt Casc Input Prgm—The remote cascade setpoint control function was programmed but no remote cascade setpoint analog input was configured. No Aux Analog Input—The auxiliary control function was programmed but no
auxiliary analog input was configured.
KW & Aux Config for Aux—The auxiliary control function was programmed to use the KW analog input but an auxiliary analog input was configured also. With this configuration, only the KW analog input is used for the auxiliary
controller.
No Rmt Aux Input Prgm—The remote auxiliary setpoint control function was programmed but no remote auxiliary setpoint analog input was configured. No Rmt Extr/Adm Input—The remote extr/adm setpoint control function was
Function Key Program Errors
Identical Function Keys—Both function keys were programmed for the same function.
No F-Key Relay Prgmd—A function key was programmed to energize a relay but no relay outputs were configured for F3 or F4 key relays.
F3 Key Program Error—The F3 key was programmed for a function that is not also programmed to be used. Either F3 was mis-programmed or the function required was mis-programmed. For example, the F3 key is programmed for Remote Cascade Setpoint Enabled but Remote Cascade Setpoint was not programmed under the Cascade Program Block.
F4 Key Program Error—The F4 key was programmed for a function that is not also programmed to be used. Either F4 was mis-programmed or the function required was mis-programmed. For example, the F4 key is programmed for Remote Cascade Setpoint Enabled but Remote Cascade Setpoint was not programmed under the Cascade Program Block.
Relay Program Errors
Relay #x Program Error—The specified relay was programmed for a function that is not also programmed to be used. Either the relay was mis-programmed or the function required is mis-programmed. For example, relay #1 is
programmed for Remote Cascade Setpoint Enabled but Remote Cascade Setpoint was not programmed under the Cascade Program Block.
Readout Program Errors
Readout #x Program Err—The specified readout was programmed for a function that is not also programmed to be used. Either the readout was mis-
programmed or the function required is mis-programmed. For example, readout #1 is programmed for Cascade Setpoint but Cascade Control was not programmed under the Cascade Program Block.
