Nomenclature
■Factory Settings
The following table shows the timer settings when it is shipped. Please change the settings as necessary to suit the system before opera-
tion. Settings and the display receive power from the internal battery and are therefore unaffected by external power interruptions.
Note: With the initial settings, there will be no output even if the power supply is connected. External inputs and outputs cannot be used
without a power supply.

Key protect level Locks certain keys to prevent acci-
dental operation. The key protec-
tion level, kP-1 to kP-4, determines
which keys are locked when the
key protection input is ON. The

■Examples
Run Mode
Changing the Set Value
To change the set value from 3 hr 5 min to 4 hr 5 min, press the 3
key so that the number 4 appears in the hour’s place.
•Pressing keys 1 through 4 increments the corresponding col-
umn by 1.
•The columns can be changed in any order, but the output will
be turned ON if the set value is less than the present value.
•Nonsignificant zeros are suppressed on the set value display.
Note: Read Changing Set Values in the Precautions section,
page 16, before changing the Timer set value during op-
eration.
Setting Mode
Changing Settings in the Set Mode
1. Press the MODE key to switch from run mode to set mode.
•The Timer will continue operation if switched from run mode
to set mode during operation.
•The MODE key will be locked if the key protection function is
enabled.
•Settings changed in the set mode are not effective until run
mode is entered. As the operating conditions will change in
this case, always reset operation with the RESET key or a re-
set input.
2. Press the MODE key to scroll successively through the items
that can be set.
3. Changing the selected item
•Press the MODE key until the desired item appears.
•Change the item setting by pressing keys 1 through 4. (Press
the DISPLAY key to switch back from set mode to run mode.)

Note: A twin timer can be created by using one of the repeat modes. For example, if the set value is 60 s and the one shot time is 10 s in
repeat mode, the control output will turn OFF for 50 s and ON for 10 s. (In the first cycle, however, the control output will turn OFF
for 60 s.) In this way, the work of two timers can be performed by a single timer.
Output mode d: Signal OFF delay (Timer resets when power comes ON.)

Precautions
■Power Supplies
•The input circuit is not insulated from the power supply circuit.
The internal circuit might be damaged by a surrounding AC cir-
cuit, so use an insulated AC power supply with equipment con-
nected to the input circuit.
•If power is interrupted for less than 10 ms, operation will continue
normally. If power is interrupted for between 10 and 500 ms, op-
eration will be inconsistent, and timing may stop or reset, de-
pending on the mode.
•Connect the power supply voltage through a relay or switch in
such a way that the voltage reaches a fixed value immediately.
•Depending on switching frequency, current surges may degrade
relay contacts; relays with a capacity greater than 10 A are rec-
ommended.
■Input and Output
•Do not use external sources to increase the voltage of input sig-
nals (control signal, reset, gate, and key protection).
•Be sure that the load of the control output (contact, transistor) is
less than the maximum values indicated in the specifications. If
the output load exceeds the recommended value, the life span of
the contact output type will be shortened dramatically, and the
transistor of the transistor output type will be damaged.
•The transistor output is insulated from the internal circuitry by a
photocoupler, so either NPN or PNP transistors can be used.
■Self-diagnostic Function
•The following displays will appear if an error occurs. The present
value and output enter the same status as after pressing the RE-
SET key.
■Changing Set Values
•The Timer set value can be changed while the timer is operating,
so a high value can be set temporarily to inactivate the timer, or
a low value can be set to activate the timer more quickly. (If the
set value is changed accidentally during operation, the timer
might be activated. Therefore, turn the key protection input ON
unless the set value is being changed.)
•To avoid changing the output when changing the set value, it is
recommended to begin changing the set value by entering a
large number in the higher digit.
■Operation with a Set Value of 0
•Operation with a set value of 0 will vary depending on the output
mode. For details, refer to Timing Charts.
■Operating Environment
•When using the Timer in an area with much electronic noise,
separate the Timer, wiring, and the equipment which generates
the input signals as far as possible from the noise sources. It is
also recommended to shield the input signal wiring to prevent
electronic interference.
•Organic solvents (such as paint thinner), as well as very acidic or
basic solutions might damage the outer casing of the Timer.
■Other
•When the Timer is installed in a control box and tests are con-
ducted which may damage the Timer’s internal circuitry (for ex-
ample, a test measuring the maximum voltage difference
between the control circuit and metal components), remove the
Timer from the control box or short circuit the terminals.
