Winland EnviroAlert EA200 Quick Start Manual

COMMON MISTAKES AND HOW TO AVOID THEM
"De-Energize" vs. "Energize"
• "De-Energize" means the relay will be OFF under normal conditions and will switch ON when there is an alarm. This is
the default state and will correspond with the legend on the circuit board (N.O. and N.C.).
• "Energize" means the relay will be ON under normal conditions and will switch OFF when there is an alarm or if power
is lost, providing power-supervision. However, this will reverse your N.O. and N.C. contacts. In either case, you still
have both sets of contacts. The AUX relay cannot be configured in this way.
Zone # vs. Output #
These directly correspond. Zone 1 uses the Output 1 relay. Zone 2 uses the Output 2 relay. Using Zone 2, but wiring to your
alarm panel using the Output 1 relay will not work. To cover all zones with a single relay, use the AUX relay.
"no" in Programming
To program a zone, press the ZONE button. The active zone will be flashing. Select the zone number using INCREASE or
DECREASE, and then press ENTER. You will then see the word "no" flashing. This means "not operational"
and indicates the zone is currently o . When you see this flashing, press INCREASE or DECREASE to scroll
through your sensing options. Zones with no probe attached should be turned o . If you are trying to
turn a zone o , select "no" here.
Temperature Reading is Not Accurate
If the reading does not match your temperature reference, ask yourself the following questions:
• Is it programmed as the correct sensor type (Figure 2) and in the correct zone? If the displayed temperature is not even
close, this is most likely the problem.
• Has the temperature reference been calibrated, and is it known to be accurate?
• Is the reference probe in exactly the same place as the EA200/400 probe? It is normal for the temperature in a climate
controlled room to vary by several degrees.
If you need to match the EA200/400's reading to a reference, use the OFFSET feature to do this. Ensure you have a known-
good calibrated reference or you may be unintentionally changing an already accurate reading.
Reading the LCD screen:
• Zone 2 current temp is 121° F
• Zone 2 high limit is 168°
• Zone 2 low limit is 115°
• The console is Locked
• Zone 2 programmed for REDprobe
• De-energized means relay is OFF under
normal conditions
• An hour glass indicates an alarm delay (up
to 120 minutes / zone)
• A solid bell indicates an alarm delay
• A flashing bell indicates active alarm
• Press and simultaneously release Enter
and Alarm Silence buttons to Lock and
Unlock the console.

LWAYS EST THE YSTEM
Test the system to ensure proper operation prior to leaving the job site. To test the system, either change the probe's
temperature so it exceeds your limits, or change the limits to simulate an alarm. If a delay has been programmed, take the
delay out, test the unit, and then put the delay back in.

REEZER OOLER ONITORING
Never install the EnviroAlert console in a cooler or freezer (condensing environment). Instead, use a remote probe (TEMP-L-S
or TEMP-L-W) and program your zone accordingly. Extend the length of probe wiring up to 1,000' (304.8m) using 22-18 AWG
twisted pair.

VOIDING ALSE LARMS ON A OOLER OR
Both the EA200 and EA400 o er an alarm delay from 0-120 minutes for each zone. When a cooler or freezer door is opened,
the temperature will rise and the probe will detect that rise. Freezers periodically need to enter a defrost cycle which may
also cause the temperature to rise above your limits. Set delays to avoid nuisance alarms under these normal circumstances.
We cannot advise you on what to set for delays or limits.
