Operation - Viessmann 4701 Bedienungsanleitung

This output is used to operate latching relays. The contact is turned on for ca. 250 ms, when the signal
reaches its respective end position.
With these contacts you can use the information about the position of the signal to switch off the rail
voltage, or in other control systems, for example a brake generator. Due to the low maximum load of the
contacts and the short pulse length, it is important to use a relay (e. g. the Viessmann electronic relay, item
5552 for items 4700 and 4701 resp. item 5226 for item 4702) as shown in fig. 9/10.
The default function of the outputs is set for all signal types as follows:
- Output with blue wire: When activating Hp1/Hp2 (via the wire with the green marking or switching
command with green button) there will be a positive voltage of ca. 16 V to 20 V present for about 0.25
seconds after the signal movement.
- Output with the purple wire: When activating Hp0 (via the wire with the red marker or switching command
with red button) there will be a positive voltage of ca. 16 V to 20 V present for about 0.25 seconds after
the signal movement.
- The black wire is the common ground.
Please note that you may select a different operating mode for signals with two uncoupled semaphore
arms in CV 38. This facilitates the option of linking an output with the Hp2 aspect.
4.10 Other functions of the switching outputs
Besides the switching pulse already described, the outputs can also be set to continuous mode with various
commands (refer to CV 38). The outputs can be digitally switched as continous outputs.
You will find more options under CV 38 in the CV-table.
4.11 Feedback via RailCom
The signal sends via the RailCom protocol the following information to the digital command station:
- Aspect of the signal
- CV contents

5. Operation

5.1 Operating the signal
Press the appropriate button on the push-button panel (analogue use) or send an appropriate request/
order to the address of the signal (digital use). The signal drive now turns the signal with a realistic speed.
This operation takes ca. 1.5 seconds. The motor drive accepts other commands during switching.
5.2 Signal bouncing for upward and downward movement
Semaphore signals allow the simulation of the typical bouncing effect of the semaphore arms.
For fast and simple use – even without a digital control system – three different motion sequences are
stored in the memory chip of the signal.
Profile 1: "Weak bouncing" with 2 bouncing moves at the end of the signal arm movements.
Profile 2: "High bouncing movements" with a more pronounced, but somewhat slower bouncing move-
ment compared to profile 1.
Profile 3 "No bouncing" with slow upward and downward movements of the signal arm without any
bouncing.
To select the motion sequence you prefer: Connect the 2 electrical power supply cables of the semaphore
signal to the 2 power supply contacts of your transformer (e. g. item 5200).
Connect the two data line cables of the semaphore signal to each other and afterwards connect them both
to one of the two power supply contacts of the transformer. After about 1.5 seconds the semaphore arm
starts moving in one of the three possible motion sequences - up to five times.
Disconnecting and reconnecting the two data line cables to the transformer again means that after 1.5
seconds the semaphore arm will start moving – now with the next different motion sequence.
Disconnecting the data cables of the semaphore signal from the transformer means that now the motion
sequence you have just watched before is stored in the semaphore signal´s memory chip. Repeat these
steps until you have found the motion sequence 1, 2 or 3 you prefer. Remove the 2 electrical power supply
