Benefits and advantages
Easy Connect Technology
Tool-free wiring and excellent vibration resistance. Push-in
terminals provide connection of wires up to 2 x 0.5 - 1.5 mm²
(2 x 20 -16 AWG), rigid or fine-strand with or without wire
end ferrules. The extended type designators for products with
push-in terminals are indicated by a P following the extended
type designator e.g. CT-xxS.xxP.
Double-chamber cage connection terminals
Double-chamber cage connection terminals provide
connection of wires up to 2 x 0.5-2.5 mm² (2 x 20-14 AWG)
rigid or fine-strand, with or without wire end ferrules. Potential
distribution does not require additional terminals. The
extended type designators for products with double-chamber
cage connection terminals are indicated by a S following the
extended type designator e.g. CT-xxS.xxS.
Time range preselection and fine adjustment
Direct assignment of the preselected time range to the fine
adjustment potentiometer scale by multicolor scales.
Higher utility class
The Easy Connect Technology provides excellent vibra-
tion resistance with gas tight push-in terminals – the right
solution for harsh environment. Selected products of the
electronic timers and measuring and monitoring relays comply
to the latest rail standards NF F 16-101/102, EN 45545, EN
50155 and more standards which are relevant for railway
applications. Find more inforamtion in the rail brochure

This function requires continuous control supply voltage for timing. Timing
begins when control supply voltage is applied. When the selected time delay is
complete, the output relay energizes. Timing can be paused by closing control
input. The elapsed time t1 is stored and continues from this time value when the
control input is re-opened.

This function requires continuous control supply voltage for timing. If control
input is closed, the output relay energizes immediately. If control input is opened,
the time delay starts. When the selected time delay is complete, the output relay
de-energizes.
If control input recloses before the time delay is complete, the time delay is reset
and the output relay does not change state. Timing starts again when control
input A1-Y1/B1 re-opens. If control supply voltage is interrupted, the output relay
de-energizes and the time delay is reset.
OFF-delay

Supply
Output
t
The OFF-delay function without auxiliary voltage does not require continuous
control supply voltage for timing.
Applying control supply voltage, energizes the output relay. If control supply
voltage is interrupted, the OFF-delay starts. When timing is complete, the output
relay de-energizes. If control supply voltage is re-applied before the time delay is
complete, the time delay is reset and the output relay remains energized. Control
supply voltage must be applied for the minimum energizing time (200 ms), for
proper operation.

the time delay starts. When the selected time delay is complete, the output relay
de- energizes.
If control input closes before the time delay is complete, the time delay is reset
and the output relay does not change state. Timing starts again when control
input reopens.
Pause timing / Accumulative OFF-delay: Timing can be paused by closing control
input X1-Z2. The elapsed time t1 is stored and continues from this time value
when X1-Z2 is re-opened.
This can be repeated as often as required.
If control supply voltage is interrupted, the output relay de-energizes and the
time delay is reset.

This function requires continuous control supply voltage for timing. If control
supply voltage is applied, opening control input energizes the output relay
immediately and starts timing. When the selected pulse time is complete, the
output relay de-energizes.
Closing control input, before the time delay is complete, de-energizes the output
relay and resets the time delay. If control supply voltage is interrupted, the output
relay de-energizes and the time delay is reset.

This function requires continuous control supply voltage for timing. If control
supply voltage is applied, closing control input energizes the output relay
immediately and starts the pulse time t1. When t1 is complete, the output
relay de-energize. Re-opening control input energizes the output relay
immediately and starts the pulse time t2. When t2 is complete, the output relay
de-energizes. t1 and t2 are independently adjustable. If control input changes
state before the pulse time is complete, the output relay de-energizes and
the pulse time is reset. If control input changes state again, the interrupted
pulse time restarts. If control supply voltage is interrupted, the output relay
de-energizes and the time delay is reset.

This function requires continuous control supply voltage for timing
. Applying control supply voltage energizes the star contactor
connected to output 1 and begins the set starting time t1. When
the starting time is complete, the first output de energizes the star
contactor.
Now, the fixed transition time t2 of 50 ms starts.
When the transition time is complete, the second ouput energizes the
delta contactor. The delta contactor remains energized as long as
control supply voltage is applied.

Time sector ≠ 300 hTime sector = 300 h
This function is used for test purposes during commissioning and
troubleshooting.
If the selected max. value of the time range is smaller than 300 h (front-
face potentiometer “Time sector” ≠ 300 h), applying control supply
voltage energizes the output relay immediately. Interrupting control
supply voltage, de-energizes the output relay.
If the selected max. value of the time range is 300 h (front-face
potentiometer “Time sector” = 300 h) and control supply voltage is
applied the output relay does not energize.
