3.5.4 Testing relay outputs
Relay outputs are used to generate alarms or to identify trip conditions. Download a
program into the device which allows setpoints to be checked by applying input signals
(e. g. program TESTE.EDT in the DEMO directory).
The program offers two lower trips at 20 % and at 40 % plus two high trips at 60 % and
at 80 % with a deadband (hysteresis) of 1 % (pulse stream normally active). A red LED
is assigned to each output to light up on alarm.
After finalizing the output test download your operating program and replace the jumpers
as shown in section "Functional test – Generals".
3.5.5 Testing LEDs
Front LEDs are used to indicate the relay status (red). A green LED can be employed to
indicate the status of the self monitoring feature.
The LEDs can also be used to fulfil other tasks e. g. all LEDs flash: device fault. The
display will then show the error code (see section "Calibration").
LEDs can be tested together with the relays or by placing the MODE jumper in position
4–5 and the TEST jumper X2 to 1–2. The 4 LEDs will then light up in sequence.
3.5.6 Testing the display
The front panel display is used to read measured values, device parameters or trip
settings (top line 4 digits plus sign).
The bottom line offers status indication. An alpha character and 2 digits show which
value is being displayed in the upper line.
Example
T01 = temperature in input 1
L01 = low trip for input 1
The display can be tested together with the push buttons as shown in section "Testing
Push Buttons" or by placing the MODE jumper in position 4–5 and the TEST jumper X2
to 1–2. The display segments will then be turned on.
