KELD KLT11BB-WXYZ Operating instructions

Specification and Operating Instructions
KLT11BB Temperature Digital Controller
Description
Installation
NOTE: Unit must be mounted away from vibration, impacts,
water and corrosive gases.
Cut hole in panel 2.80 x 1.14 inches)
Apply silicone (or rubber gasket) around the perimeter of
the hole to prevent leakage.
Insert unit into hole of panel.
Slide removable fitting clips onto unit from the back until
secure to panel.
Remove back cover to wire unit
Wiring diagram is displayed on the top of the unit
Note: DO NOT INSTALL PROBE CABLE NEAR POWER
CABLES.
Replace cover once wiring is completed.
The KLT11BB is designed for many heating and cooling,
high temperature applications. The probe temperature is
displayed on the bright 3-digit display. The user is able to
program 18 different parameters including set point,
hysteresis, cycle time and ambient probe adjustment using
the silicone front keypad. The unit features error or alarm
warning, internal buzzer and password protection. Select
between thermocouple J, K or S type, temperature display in
ºC or ºF and 115VAC, 230VAC or 12VAC/DC power supplies.
The model reference is given by: KLT11BB - WXYZ

If d0 = Ht and TS is the temperature of ambient probe:
If TS >= SP the load is disconnected
If TS <= SP-r0 the load is connected

If A3=OFF alarm 1 disabled
IfA3=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

Maintenance, cleaning and repair
After final installation of the unit, no routine maintenance is
required.
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 UPand DOWN
Keys.
•Press SET to view the value on the display.
• The value can be modified with the UPand 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:
• Er = Memory Error
• oo = Open Probe Error
• -- =Ambient temperature out of range
In case of alarm or error the internal buzzer is activated. The
buzzer can be silenced pressing the SET and DOWN arrows
at the same time (when a new alarm or error occurs the
buzzer sounds again).
Clean the surface of the display controller with a soft and
damp cloth. Never use abrasive detergents, petrol, alcohol
or solvents.
All repairs must be made by authorised personnel.
