. SAFETY RULES
Before using the device, please read this manual carefully, and:
a) in order to avoid electric shock or damage to the device mechanical and electrical assembly
should be commissioned to qualified personnel
b) before turning on the power, make sure that all cables have been connected correctly
c) before modifying cable connections, disconnect the voltage connected to the device
d) ensure proper working conditions, compliant with the technical data of the device (chapter 4, supply voltage,
humidity, temperature, etc.), do not expose the device to direct and strong influence of heat radiation
2. ASSEMBLY RECOMMENDATIONS
The device has been designed to provide an adequate level of resistance to most of the disturbances that can
occur in industrial and home environments. In environments with an unknown level of interference, it is
recommended to use the following measures to prevent any possible disruption of the device's operation:
a) do not supply power to the device from the same lines as large capacity devices without proper mains filters
b) use shielding of power, sensor and signal wires, and screen-grounding
should be single-point, made as close as possible to the device
c) avoid laying measuring (signal) wires in the immediate vicinity and parallel to
power and supply cables
d) it is recommended to twist signal wires in pairs or use a ready UTP wire
e) Use the same cables for resistance sensors in a -wire connection
f) avoid the proximity of remotely controlled devices, electromagnetic meters, high power loads,
loads with phase or group power control and other devices generating large impulse noise
g) ground or neutralize the metal rails on which the rail devices are mounted
Before starting working with the device, remove the protective foil of the LED display.

smart logic parameters
- programmable operation characteristics (process controller with timer, up to 6 segments, including
segments of ramping type-slope for heating/cooling or cooling/defrosting, SP setpoints with ON-OFF or
PID control, selection of the auxiliary output and its condition, displaying the remaining time for the entire
segment or after exceeding the SP, etc.)

To perform the wiring assembly for AR632.B follow the instructions below:
- unscrew 4 screws in the front plate and remove it from the device
- the device can be screwed to the base with 4 screws in the mounting holes
- unscrew 1 screw on the display board and carefully slide the board out of the mounting sockets
- connectors for signal cables, power supply and relay outputs are available
- lead the electric wires into the housing through cable glands (and tighten the optional RJ45 pin)
- after assembly, assemble the device in the reverse order to that described above

7.1. FUNCTION KEYS AND BINARY INPUT
Independent function keys [F] (not available in the AR602.B) and [SET] as well as the BIN binary input are used to
quickly run the programmed functions (with parameters 64: Fun F, 66: FunS and 65: Funb , described in chapter 8).
The BIN digital input cooperates with a bistable signal, i.e. the supplied signal (voltage or switch) must be
permanent (on/off type, active level: short-circuit or < 0.8V). Moreover, BIN has priority higher than the [F] and
[SET] keys. Activating or stopping the function is signaled by appropriate messages on the lower display
(described in Table 8 and chapter 10). The action for [F] and [SET] is performed only in the mode with
measurement display (after holding time> 1.5 sec), for BIN - always (in every operating state).
8. SETTING CONFIGURATION PARAMETERS
