If functioning with 2 measurement inputs:
top probe error
Remedies:
• the same as the previous case but relative to the top probe
Main consequences:
• the top output will be deactivated
• the acoustics output and the buzzer output will be acti-

vated

Pr2

floor probe error (only if functioning with 2 measurement
inputs)
Remedies:
• the same as the previous case but relative to the floor probe
Main consequences:
• the floor output will be deactivated
• the acoustics output and the buzzer output will be acti-

vated

When the causes of the alarm have disappeared, the instrument will go
back to normal functioning.

VARIOUS
restraint between the power distributed to the top and power distributed to the floor
0 = no restraint
1 = the modification of the power supplied to an output automatically causes

the supply of the maximum power to the other

2 = the modification of the power supplied to an output causes an automatic

adaptation of the power supplied to the other such to guarantee that the
sum of the two percentages is always 100

cycle time for the top output and floor output switch-on, see also Po1 and Po2
event that causes the activation of the rapid heating function

for 1s (make sure that the instrument is in on state and that no

procedure is in progress)

2 = pass from stand-by state to on state
3 = press

for 1s (make sure that the instrument is in on state and that no

procedure is in progress) or pass from stand-by state to on state

temperature of the chamber over which the rapid heating function is inter-
rupted (relative to the work set-point i.e. “work set-point - c3”)

ber temperature alarm is activated; with 2 measurement inputs, temperature of

point + A1”)

on/stand-by input polarity
0 = live input active
1 = non-live input active
effect caused by the activation of the multifunction input

chamber light to switch-on and the successive activation will cause its switch-
off

2 = BUZZER, ACOUSTIC OUTPUT AND BUZZER OUTPUT DEACTIVATION - the

activation of the input will cause deactivation of the buzzer, the acoustic
output and the buzzer output (activate the input again to deactivate these
utilities again)

Digital inputs: 2 inputs:

• on/stand-by input in high voltage (230 VAC) with

configurable polarity

• multifunction input, for NO/NC contact (potential-

free contact, 5 V 1 mA).

Range of measurement: from -99 to 800 °C (from -99 to 999 °F) for
J thermocouple, from -99 to 999 °C (from -99 to 999 °F) for K thermo-
couple.
Resolution: 1 °C/1 °F.
Digital outputs: 6 relays:

• top (relay K1): 8 A res. @ 250 VAC (contact in

exchange)

• floor (relay K2): 8 A res. @ 250 VAC (contact in

exchange)

• alarm (relay K3): 8 A res. @ 250 VAC (NO

contact)

contact)

• on/stand-by (relay K6): 8 A res. @ 250 VAC

The maximum current accepted on clamp 23 is 10 A.
Other outputs: buzzer output (12 V, max. 20 mA); the output is acti-
vated during alarms and errors, with continuous contribution.
Serial port: port for the communication with the supervising system
(through a serial interface, via TTL, with MODBUS communication
protocol) or with the programming key.
