Introduction to Indigo 500 Series
Transmitters
Vaisala Indigo 500 Series Transmitters are industrial-grade, robust transmitters that
accommodate 1 or 2 Vaisala Indigo compatible probes for humidity, temperature, dew point,
carbon dioxide, hydrogen peroxide, and moisture in oil measurements. The transmitters can
display measurements on the spot as well as transmit them to automation systems through
analog signals, relays, or Modbus TCP/IP protocol.
The Indigo 520 transmitter has 2 probe connections and a touchscreen display.

2. Cut o 10 mm (0.39 in) of the line and neutral wires. Leave the grounding wire 55 mm
(2.17 in) long.
Make sure that the grounding wire is longer than the line and
neutral wires. Under mechanical stress, the grounding wire must be the last
to disconnect from the protective ground terminal.
CAUTION!
3. Strip the ends of the individual wires to expose the conductors for a length of 8 mm
(0.32 in).

Verifying tightness of cable glands
To maintain enclosure tightness and provide strain relief to the cables, all cable glands must be
tightened. Unused cable glands must remain plugged.
1. Check every cable gland that is in use:
a. Pull on the cable to verify that the cable is securely held by the cable gland.
b. Tighten the cable gland if the cable moves.
2. Check that every unused cable gland is plugged and tightened.
14 M212290EN-B

Attaching probes
Attach only Vaisala Indigo compatible probes to the transmitter.CAUTION!
The IP classification of probes is valid only when the probes are
attached to the probe connection cable.
CAUTION!
If you want to configure the probe settings, such as purge interval, you must do
that before attaching the probe to the transmitter. To configure the probe, you
can use the free Vaisala Insight PC software. For more information, see your
probe's user guide and visit www.vaisala.com/insight.
When the probe connection cables have been wired to the transmitter, you can attach and
detach probes both when the transmitter power is on and when it is o. If the power is on
while you attach or detach a probe, the transmitter shows a notification about the probe. If
you have configured the transmitter to use outputs, the transmitter also notifies you of the
state of the outputs.

Starting up transmitter using touchscreen
display
1. Remove the plastic protection cover on the touchscreen display.
2. Power up the transmitter.
Powering up takes some minutes.
After the power-up, the Measurements (Home) view opens, showing the 2 preferred
measurement parameters from each connected probe.
3. Select the configuration menu symbol at the upper right corner of the touchscreen.
4. The default language of the user interface is English. If you want to use another language,
select it in Transmitter > Language.
Your transmitter is now ready for operation. You can next go through these additional settings:
•Date and time
•Network
16 M212290EN-B

For information on configuring the home views and outputs on the touchscreen, see Indigo
520 User Guide (M212287EN), available at www.vaisala.com.
Configuring network connection on touchscreen
Before you start, find out from your local network administrator whether your transmitter uses
dynamic or static network settings.
• Dynamic network settings are automatically assigned by a DHCP server each time the
transmitter is powered up.
• Static network settings must be configured manually. Ask your local network
administrator for the settings.
Figure 5 Network settings on touchscreen
1. Make sure that the Ethernet cable is connected to the transmitter.
The Ethernet connector's LED lights up.
2. Select the configuration menu symbol at the upper right corner of the touchscreen.
3. Select Transmitter > Network.
4. Make sure that Network o/on is set on.
5. Select the setting type:
• Select DHCP if the transmitter is in a network that assigns network settings
automatically.
• Select Static IP to configure network settings manually.

ENGLISH

6. If you selected Static IP, fill in the rest of the fields with information provided by your local
network administrator:
IP address
The four part network ID of the transmitter.
Subnet mask
Used together with the IP address to determine which network the transmitter is a
part of.
Gateway
IP address of the server that enables the transmitter to access other networks.
DNS servers
Public computer server that translates the domain name of the transmitter into an IP
address.
7. Scroll to the end of the screen and select Apply to save your changes.
Setting date and time on touchscreen
Figure 6 Date and time settings on touchscreen
The transmitter uses UTC (Coordinated Universal Time) internally. Time and time
stamps in the touchscreen are shown according to the time zone set in
Transmitter > Date and time.
1. Select the configuration menu symbol at the upper right corner of the touchscreen.
2. Select Transmitter > Date and time.
