6 ALARMS

6.1 Alarms

MEANING

Compressor LED

if it is lighted, the compressor will be ON

if it flashes, a compressor delay will be running (look at the parameters

C0, C1, C2 and C4)

Defrost LED

if it is lighted, the defrost output will be activated

if it flashes:

• a defrost delay will be running (look at the parameters C0, C1, C2 and

C4)

• the dripping will be running (look at the parameter d7)

Evaporator fan LED

if it is lighted, the evaporator fan will be ON

if it flashes, the after dripping evaporator fan delay will be running (look

at the parameter F5)

LED

(1) you can set the working setpoint between the limits you have set with the param-

eters r1 and r2.

4 CONFIGURATION PARAMETERS

4.1 How to set the configuration parameters

Configuration parameters are arranged on two levels.

If you have to gain access the first level:

• press

and for 4 s : the instrument

will show

If you have to select a parameter:

• press

If you have to modify the value of the parameter:

• press

and or

If you have to gain access the second level:

• gain access the first level

• press

or for selecting

• press and or for setting “ -19 “

• press

and for 4 s : the instrument

alarm

REASONS

there is the corruption

of the configuration

data of the memory of

the instrument

• the kind of cabinet

probe you have con-

nected is not right

• the cabinet probe

plays up

• the connection in-

strument-cabinet

probe is wrong

• the cabinet tempera-

ture is outside the

limits allowed by the

working range of

the instrument

• the kind of evapora-

tor probe you have

connected is not

right

• the evaporator

probe plays up

• the connection in-

strument-evaporator

probe is wrong

• the evaporator tem-

perature is outside

the limits allowed by

the working range

of the instrument

REMEDIES

switch off the power

supply of the instru-

ment: unless the alarm

disappears, you will

have to change the

instrument

• look at the param-

eter /0

• test the integrity of

the probe

• test the instrument-

probe connection

• test the temperature

close to the probe (it

has to be between

the limits allowed by

the working range)

• look at the param-

eter /0

• test the integrity of

the probe

• test the instrument-

probe connection

• test the temperature

close to the probe (it

has to be between

the limits allowed by

the working range)

EFFECTS

• you can not gain

access the setting

procedures

• the compressor, de-

frost output and

evaporator fan will

be forced OFF

• the alarm output

will be activated

• the alarm output

will be activated

• the compressor will

be forced to the sta-

tus you have set

with the parameter

• if the defrost is run-

ning, it will immedi-

ately end

• the defrost will

never be activated

• the alarm output

will be activated

• if the parameter F0

has value 0, the

evaporator fan will

work in accordance

with the compres-

sor, except what

you have set with

the parameters d7,

F4 and F5

• the defrost will end

by time (parameter

d3)
