17.0 ERROR MESSAGES
17.1 Overview
If the instrument detects an error during the RUN, INITIALIZE, or SETUP modes, it stops operation and enters its
ERROR mode as described in “Operating Modes” in Section 3.1.
The most frequent causes of error messages are:
• Wiring/electrical connection problems
• Misplaced address jumpers when installing or removing channel circuit boards
• Swapping channel circuit boards between instruments
17.2 Error Message List
Error 05, DIVIDE BY ZERO A Mathematics Virtual channel has attempted to divide by zero.
Error 07, SQUARE ROOT A Mathematics Virtual channel has attempted to take the square root of a
negative number.
Error 09, LOG/LN A Mathematics Virtual channel has attempted to take the logarithm of
either zero or a negative number.
Error 20, CHANNEL >MAXCH An invalid channel number has been encountered by the instrument.
Restart the instrument. If this error persists, contact Cooper with the
information found in the SYSTEM MENU-SOFTWARE REV. menu item.
Error 21, BLOWN STACK The instrument’s software stack has overflowed. Restart the instrument. If
this error persists, contact Cooper with the information found in the
SYSTEM MENU-SOFTWARE REV. menu item
Error 22, TYPE NOT FOUND The instrument has not been programmed to understand the type of
channel. Contact Cooper with the information found in the SYSTEM
MENU-SOFTWARE REV. menu item
Error 23, CAN’T RENDER FS The full-scale value of the transducer cannot be rendered on the display
with the selected DISPLAY SETUP menu settings. Change the DISPLAY
SET UP menu settings. Change the DISPLAY SETUP menu settings to
better match the transducer’s capacity.
Error 24, SIG.MOD CRC ROM A checksum error occurred while reading a Signature Module’s read-only-
memory. Check the wiring and restart the instrument. This error may
occur with very long cable lengths.
Error 25, SIG.MOD CRC READ A checksum failure occurred reading data from a Signature Module.
Check the wiring. This error may be caused by a faulty Signature Module.
Error 26, NO SIG.MOD. No Signature Module was detected during UPDATE SIG.MOD. or
DEFAULT SIG.MOD. Check wiring.
Error 27, S.EE WRITE NAK The channel’s EEPROM could not be detected during a write operation.
Check that the channel’s address jumpers are set properly so that each
card has a unique address.
Error 28, S.EE READ NAK The channel’s EEPROM could not be detected during a write operation.
Check that the channel’s address jumpers are set properly.
Error 29, S.EE VERIFY FAIL A verification failure occurred during a write operation to the channel’s
EEPROM. Restart the instrument.
Error 30, S.EE ERASE NAK The channel’s EEPROM could not be detected during an erase operation.
Check that the channel’s address jumpers are set properly.
Error 31, BLANK IDENT The channel does not appear to have been installed properly. This occurs
if you swap Input or Output boards without using SYSTEM MENU-
INSTALL CHANNEL to format the channel’s EEPROM.
Error 32, BOGUS EE ADDR An invalid address has been passed to the programmer. Restart the
instrument. If this problem persists, contact Cooper with the information
found in the SYSTEM MENU-SOFTWARE REV. menu item.
Error 33, SIG.MOD WIRES The instrument has detected that the (+)Signature and (-)Signature pins
(labeled as “+MEM” and “–MEM”) are likely reversed.
Error 34, SIG.MOD MISMATCH The excitation type byte found inside a Signature Module indicates that the
channel is not designed to operate with that type of transducer.
Error 35, BOGUS MENU TYPE A menu contains an invalid menu type. Contact Cooper with the
information found in the SYSTEM MENU-SOFTWARE REV. menu item.
Error 36, BAD EE TABLE The instrument doesn’t understand the EEPROM type setting for the
channel. Contact Cooper with the information found in the SYSTEM
