Test Mode Using the Visograph • 51
3. Once in the Command screen, press and hold T6 Te st for
three (3) seconds to enter Test mode, the first stage is the
Relay Tests.
a. If there are no configured relays, Visograph will
display a message No Configured Relays. Otherwise
the first relay test is the Enable relay.
b. Use the T4 key to cycle the relay through active/
inactive states and then check the operation of the load it
is controlling, or check the relay contacts with a
multimeter for operation. After finishing each relay test,
use the T7 Next Test Key to advance to the next
configured relay. At the end of the relay tests, use the T8
key to advance to the next section.
4. Digital Inputs Test - Use this section to verify the operation
of any connected and programmed digital inputs. If there are
no digital inputs configured, Visograph will display this with
a message. Toggle the switch or input connected, then verify
on screen that the status changes.
a. Use the T8 key to move to the next section of tests after
digital input testing is complete.
5. Temperature Inputs Test -This section is designed to allow
the user to test each of the configured temperature sensor
inputs. The test expects each sensor’s temperature to be
decreased by a delta of 10 degrees within 30 seconds in
order to display a pass message. If you do not wish to use the
delta T test, use the T6 key to advance through the sensors to
check the readings. If any sensor has an error, the error will
be displayed in the value box. Once Temperature input
testing is complete, use the T8 key to advance to the next
section of tests.
6. Pressure Inputs Tests - This section is designed to allow the
user to verify visually the value of each configured pressure
transducer. The mode also verifies that a transducer is
programmed. If no transducers are programmed, Visograph
will display a message No Configured Pressure Inputs.
After transducer testing is complete, use the T8 key to
advance to the next section of tests.
