6.1 Outline of code display
If the code display lights up during normal running, it means that a failure occurred in the F-MPC60B main unit or any peripheral equipment or any relay motion occurred. “F□” represents equipment failure and “E□” represents a relay motion.
6.2 Reading of code display and measures to be taken
1) Equipment failure
When an equipment failure is detected, the ALARM LED is lighted, the output of the equipment failure relay is output, and the code is displayed. If the code display is other than FE, the running is continued and an equipment failure code and normal operation display (measured data) are displayed as switched about once every second.

Measure to be taken
ＦＥ
Serious failure in F-MPC60B interior(error of CPU,ROM,RAM or the like)Stopped Replace the F-MPC60B Ｆ３ Unbalance in 3 phases of PT,CT signal(whether the function
is valid or invalid may be selected)
Continued Check the external wiring.
Ｆ４ Jammed CB contact opening Continued
Ｆ５ Jammed CB contact closing Continued
Check the CB ON/OFF wiring and "answer-back" signal wiring.
Ｆ６ Open circuit in CB trip coil Continued Check the trip coil system. Ｆ７ History data error(mismatch of memory check data) Continued Set the history data again.
Ｆ８
Error in F-MPC60B constant monitoring internal circuit Continued This device is normal, in the case that "F8" turned off it by pushing "the sheet switch; RST". Note 1F□
Light-up of ALARM LEDＦ９ Error in setting frequency 50/60Hz Continued ON/OFF the control power after setting the frequency to the normal level.
● F3 is reset automatically when the cause of failure is eliminated.
●F6 is reset automatically when the cause of failure is eliminated. It also goes out when the sheet switch RST is pressed in the state when the CB is OFF. (If the trip coil open circuit monitor function is not used, set “Trip coil open circuit monitoring: None” in the setting.)
● F4 and F5 go out when the sheet switch RST is pressed.
● Other than the above, execute self-hold when a failure is detected and then goes out when the sheet switch RST is pressed.
Note 1; In the case that the abnormality of the signal is detected in the analogue input circuit, digital input circuit and output relay drive circuit of this device, the Code display; " F8" is displayed in the 7-segment LED.
There is not abnormality in this device that depends on a temporary factor, in the case that F8 turns off it by pushing the return switch RST. Therefore, there is not a problem by using this device.
2) Relay motion
When any relay motion occurs, lighting of the relay motion LED and output of an alarm (trip) are performed besides the code display. Check the cause for relay motion. Description of E codes is printed on the front panel sheet.
Table 6.2 the display of the relay motion

● When PLURAL FAULTS LED’s are lit, have a code displayed as switched by pressing sheet switch ∨ or ∧.
● The relay motion display and T-link data are kept after the cause of the failure was eliminated, and they go out when the sheet switch RST is pressed. If the control power was gone in the state when the sheet switch RST has not been pressed yet, storage is done automatically, and the status before the power failure occurred is output and displayed when the control power is recovered.
● When the E code display is flickering, it means relay detection in motion. (Operates after elapse of timer time.)
Note 1: When the OC relay is actuated, the fault current value (unit A) and the motion time (unit s) are displayed as switched approximately once every second.
6.3 The method of relay test
Refer to the appendix table 4: "The relay test".
As the relay test is tested at the condition of normal state, the position of the key switch must be the normal. (When the position of the key switch is the test, the protection function of F-MPC60B does not act at all.) The note at the test
(1) The Table 6.3 shows the allowable continuous current at input circuit of the phase current. Refer to the Table 6.3 when the operation time is tested.
Table 6.3 the allowable continuous current (for the F-MPC60B that the secondary rating current is 5A.) The input current The time of the allowable continuous
current
The input current The time of the allowable continuous current
0-15A For more than 100 s 40-80A 6.3 s
15-20A 100 s 80-100A 4.0 s
20-40A 25 s --- ---
The overload capacity of the current input circuit is 200A, 1s and 2 times: 60 s as an interval. Refer to Figure 6.1 when the operation time is tested.
Figure 6.1 the overload capacity of the current input circuit
(2) The F-MPC60B has the band-pass-filter to prevent the wrong action by the harmonic current, and changes the circuit constant of the band-pass-filter using the setting value of the frequency: 50Hz or 60Hz. So, at the relay test, set up the setting value, and input the signal that has the same frequency with the setting value.
If the generator is used at the test, keep the accuracy oh frequency: ±2.5% or more less.
