KELD KLT11IB Operating instructions

Specification and Operating Instructions
KLT11IB Temperature Digital Controller
Description
Installation
The KLT11IB is designed for heating and cooling applications. The
probe temperature is displayed on the bright 3-digit display. The
user is able to program different parameters including set point,
hysteresis, alarms and probe adjustment using the silicone front
keypad. The unit features error or alarm warning, internal buzzer
(optional), configurable digital input and password protection. The
KLKey input allows an easy programming of the parameters. Select
between temperature display in ºC or ºF, display color and 230Vac,
115Vac, 24Vac/dc or 12Vac/dc power supplies.
The model reference is given by: KLT11IBXYZ
Where each sufix can take the following values:
X Display Color R=Red, G=Green, B=Blue
Y Supply Voltage 230=230Vac, 110=115Vac
24=24Vac/dc 12=12Vac/dc
Z Units C=ºC, F=ºF

d0 =
If d0 = Ht and TS is the temperature of ambient probe:
If TS >= SP the load is disconnected

Al = External alarm (if input is short-circuited)
ES = Energy Saving. Set Point value is modified in r4.
HC = if input is short-circuited, it changes to Heat or Cold

if d0 = Cold it changes to Heat mode.
If A3=OFF alarm 1 disabled
If A3=HI then a high-temperature alarm is set:
if TS >= SP+A1 the alarm 1 is activated
if TS <= SP+A1-A0 the alarm 1 is de-activated
IfA3=LO then a low-temperature alarm is set:
if TS <= SP-A1 the alarm 1 is activated
if TS >= SP-A1+A0 the alarm 1 is de-activated
The alarm 1 is not activated until the time since instrument is turn
on is higher than A2

A8 = Alarm verification time. Time since the alarm situation
occurs until its signalling.

External alarm)
Set Point (SP) is the only parameter the user can
access without code protection.
•Press SET. SP text will appear on the display.
•Press SET again. The real value is shown on the display.
•The value can be modified with the UP and DOWN arrows.
•Press SET to enter any new values.
•Press SET and DOWN at the same time to quit
programming or wait one minute and the display will
automatically exit programming mode.
Access to all code protected parameters.
•Press SET for 8 seconds. The access code value 00 is shown on
the display (unit comes with code set at 00 from factory).
• With the UP and DOWN arrows, code can be set to user needs.
•Press SET to enter the code. If the code is correct, the first
parameter label is shown on the display (SP).
• Move to the desired parameter with the UP and DOWN
Keys.
•Press SET to view the value on the display.
• The value can be modified with the UP and DOWN arrows.
•Press SET to enter the value and exit.
• Repeat until all necessary parameters are modified.
•Press SET and DOWN at the same time to quit programming or
wait one minute and the display will automatically exit programming
mode.
*The keyboard code can be reset to ZERO by turning off the
controller and turning it on again while keeping the SET key
depressed.
The led OUT indicates if the load is connected or not.
In normal operation, the probe temperature will be shown on the
display.
In case of alarm or error, the following messages can be shown (the
alarm led is ON and buzzer sounds):
• Err = Memory Error.
• ooo = Open Probe Error.
• --- = Short-circuit Probe Error.
•A1H = High temperature alarm 1.
•A1L= Low temperature alarm 1.
•A2H= High temperature alarm 2.
•A2L= Low temperature alarm 2.
•ALE = External alarm.
In case of alarm the internal buzzer and alarm led is activated. The
display shown the corresponding message. The buzzer and display
message can be silenced pressing the SET and DOWN arrows at
the same time. If alarm continues afterA8 it is signalling again.
