Warning Flags are set when either the 1303’s self-check procedures or
the Check_System interface job identify an error condition. This in turn
sets bit 6 of the Status Byte (generating a service request, if enabled)
to indicate that an error condition exists. The Warning? job can then
give more information about the cause of the error condition.
Example:
Warning?<LF>
Outputs the Warning Flags from the
1303. A “1” indicates that the flag is
set; a “0” indicates the flag is not
set.
The conditions which causes the Warning Flags to be set, and the ap-
propriate action to take, are dealt with in turn below.
Reset Done Flag
Indicates that the 1303 has completed a reset, following either the Re-
set_System interface job (
section 3.8.5
) or switching-on the 1303. This
flag is reset when the Warning Flags are read-out from the 1303.
Temperature Flag
Is set when the internal temperature of the 1303 is outside the range
+2°C to +60°C. The 1303 must not be used until the internal tem-
perature is within the normal operating limits of +5°C to +40°C. This
flag is reset when the internal temperature is again within the normal
operating limits, or by resetting the 1303, or switching the 1303 off/on.
Power Fail Flag
Is set if the power from the 1303’s transformer to the 1303 is outside
the range 13,25V to 15,75V. This flag is reset when the voltage is back
within the above range, or by resetting the 1303, or switching the 1303
off/on. If the error is persistent, have the 1303 serviced.
