¬ A voltage other than the supply voltage can be used at B1, but must be within voltages specified on timer.
T Output 2 is selectable as instantaneous contact with sliding switch (Ä) on front panel (instantaneous when switch is down, timed when switch is up).
‡ Available on multifunction "M," and single function "A" or "B" option timing relays along with code "4" (2PDT contacts). Bridge or potentiometer 10 kW, 0.25 W min. (low voltage) for external time setting. Set timer dial to 0.0.

(H) Flasher (Repeat Cycle Starting with Pulse or Pause)
The repeat cycle timer permits different settings for on and off times.
The following operating modes are possible:

Oscillating mode; repeat cycle starts with voltage applied at A1 and B1, and continues to repeat until voltage is off.

One cycle mode; started by energizing B1 with voltage on A1 and A2.

Output starts with pulse or pause (switch Ä Up or Down).

700-FSH3U provides (1) range setting for t₁ and t₂.
700-FSH3V provides (2) range settings for t₁ and t₂.

Supply Voltage Controlled, Oscillating Mode Starting with Pause — Switch Ä is Up

Supply Voltage Controlled, Oscillating Mode Starting with Pulse — Switch Ä is Down

Pulse Controlled, Output Starts With Pause (Min. Pulse AC 50 ms — DC 30 ms) — Switch Ä is Up One Cycle Mode — Voltage Supplied at A1 and A2, then Pulsing “s” to Energize B1 will Initiate One Cycle.

Pulse Controlled, Output Starts with Pulse (Min. Pulse AC 50 ms — DC 30 ms) — Switch Ä is Down One Cycle Mode — Voltage Supplied at A1 and A2, then Pulsing “s” to Energize B1 will Initiate One Cycle.

Note:If B1 is pulsed, a one full time cycle consisting of t₁ and t₂ is completed.

(Q) Off-Delay without Supply Voltage (True Off-Delay) — When input power is turned on, the output contact changes state. When the power is removed, the time delay begins. The output contact returns to shelf state at the end of the time delay.

Note:Min. pulse (tp) required:
800 ms

(Y) Star-Delta Timing Relay — When power is applied, the output contact 17/18(Y) changes state. After the time setting, the output contact 17/18(Y) returns to shelf state. After the fixed time (50… 60 ms), the output contact 17/28D changes state. Both output contacts return to shelf state whenever the power is removed.
