Returning to the initialization (State set at factory before shipment)
When returning the equipment to the initial state set at factory before shipment for some reason,
follow the following procedure.
1) Allocate STN (set value ) to one of the input intelligent terminals. (Use to
in the extension function mode to set the intelligent terminals.)
(However, cannot be used since resetting RS is initially set.)
2) Short-circuit the STN terminal and P24 (CM1*), then turn power off and on. (When the power is
turned off, do not turn it on again until the CHARGE lamp of the logic PCB goes off.)
3) Keep the STN terminal open for more than 6 seconds. (When keying, resetting, or turning power
off is performed within 6 seconds, the equipment may not be initialized.)
4) Turn the power off after more than 6 seconds. (When the power is turned off within 6 seconds,
the equipment may not be initialized.)
How to Delete Trip History Data ( , and )
To delete trip history data for some reason, follow the instructions shown below using the remote
operator (DOP or HOP) or copy unit (DRW or HRW).
1. Using the remote operator (DOP-OA) or copy unit (DRW-OA)
(1) Display
INIT TCNT
(trip history count clear) or the function mode initial setting
F-38 INIT
.
(2) Move the cursor to beneath the initial set values. Select CLR and store it.
1) Turn the power off once and then turn it on. or close the reset terminal RS-P24 (CM1*) for
approx. a second. By this, trip history data is deleted.
2) When trip history is deleted, data of [F-38] is set to [CNT]. Trip counting restarts.
2. Using high-performance remote operator (HOP-OJ) or high-performance copy unit
(HRW-OJ)
(1) Display [TCNT 0: CNT] (trip history count clear) or the function mode initial setting
[2-1 INIT].
(2) Enter a count clearing value [0: CLR] from the 10-key pad.
1) Turn the power off once and then turn it on. or close the reset terminal RS-P24 (CM1*) for
approx. a second. By this, trip history data is deleted.
2) When trip history is deleted, data of [2-1 INIT] is set to [CNT]. Trip counting restarts.
