MEA-100B
10. Interface
10-4
Terminal No. Description
13-14
[END]
Output terminal for End [END] signal.
The signal is output upon completion of the welding sequence.
Note: For timing details, see 11. Timing Chart .

Relay contact output: 24 V DC, or 250 V AC or less, 0.5 A
15-16
[NG]
Output terminal for trouble [NG] signal.
The circuit is opened when a trouble occurs.
(Preset the fault signal attribute so that the trouble signal can be output
when the fault occurs. For details, see 9. (2)

.)
The circuit is closed when [ERR RESET] is input.
Note: When the power supply of the MEA-100B is off, the circuit is
opened.

Relay contact output: 24 V DC, or 250 V AC or less, 0.5 A
17-18
[GOOD]
Output terminal for Normal End [GOOD] signal.
The circuit is closed if the current falls within the monitor range, or if the
current monitor function is not used after the welding sequence has
been completed.

Relay contact output: 24 V DC, or 250 V AC or less, 0.5 A
19
[COM]
Common terminal for input.
20
[WELD
SKIP]
Input terminal for [WELD SKIP] signal.
If this circuit is closed, the stage within the welding sequence are
skipped.
The specific operation depends on the weld skip (WS) setting, as shown
below:

WS: 0 → Skips to the next stage of the sequence.
(If WELD1 is underway, skips to COOL. If WELD2 is
underway, skips to HOLD.)

WS: 1 → Skips to HOLD.
21
[WELD
STOP]
Input terminal for [STOP] signal.
If this circuit is opened, the welding sequence including the welding
operation is immediately halted.
[E15: WELD ABORT] is given if the circuit is open during welding or
when the start signal is input. (See 12. Troubleshooting .)
22
[CNTR
RESET]
Input terminal for Counter Reset [CNTR RESET] signal.
If this circuit is closed, the total count is reset.
23
[ERR
RESET]
Input terminal for trouble reset [ERR RESET] signal.
Closing this circuit clears [NG] and [CAUTION] outputs. Note that the
outputs are cleared only if the cause of the original fault has been
rectified.
24
[STEP
RESET]
Input terminal for [STEP RESET] signal.
Closing this circuit resets the stepper number and the stepper count.
25
[COM]
Common terminal for input signals.
26
[WELD
ON/OFF]
Input terminal for [WELD ON/OFF] signal.
Opened → WELD OFF (Shuts off the welding current.)
Closed → W ELD ON (Flows the welding current.)
For the welding current to flow, the [WELD] key on the front panel must
also be ON.
