If you open the positive and negative terminals, the output is turned off, and the TOS5300 Series is
switched to Protection mode.
Open: The resistance between the two terminals is 1.2 kΩ or greater.
Short: The resistance between the two terminals is 1 kΩ or less.

I
Panel memory selection signal.
The selection signal is latched on the
rising edge of the input strobe signal to
recall panel memory.
* The selection of memory is prioritized
over TEST SEL and AUTO SEL.

L: ACW. H: DCW.
Single test selection signal and auto test
order selection signal.
If AUTO SEL specifies single test, L: ACW
and H: IR.
If AUTO SEL specifies auto operation, L:
ACW→
IR and H: IR→ACW.

If you open the positive and negative terminals, the output is turned off, and the TOS5300 Series is
switched to Protection mode.
Open: The resistance between the two terminals is 1.2 kΩ or greater. Short: The resistance between the
two terminals is 1 kΩ or less.

HV.ON
O
On during testing and when a voltage remains across the
output terminals.
On during testing, when a voltage
remains across the output terminals,
and during auto tests (AUTO TEST).
15 TEST O On during testing (excluding when voltage is rising or falling).
16 PASS O
On for at least 0.2 seconds (the PASS HOLD time) when a PASS judgment occurs.
On continuously when the PASS HOLD time is set to HOLD.
17 U-FAIL O
On continuously when an UPPER FAIL judgment occurs because a value greater than or equal to the
upper limit is detected.
18 L-FAIL O
On continuously when a LOWER FAIL judgment occurs because a value less than or equal to the lower
limit is detected.
19 READY O On when the TOS5300 Series is waiting (when it is in the READY state).
20 PROTECTION O On when protective features have been activated.
21 START I Start signal input terminal.
22 STOP I Stop signal input terminal.
23 ENABLE I
Input terminal for the start signal’s ENABLE signal. If the ENABLE signal changes, the TOS5300 Series is
switched to Protection mode.
24 +24 V — +24 V internal power supply output terminal; maximum output current 100 mA.
25 COM — Circuit common terminal.
