Operating modes
Mode ON OFF1 (On1) with r0=ind.
Relay 1 with c1=dir.
Temperature of probe 1 >= SP1+r1 -->relay 1 ON
Temperature of probe 1 <= SP1 -->relay 1 OFF
Relay 1 with c1=inv.
Temperature of probe 1 <= SP1-r1 -->relay 1 ON
Temperature of probe 1 >= SP1 -->relay 1 OFF
Relay 2 with c2=dir.
Temperature of probe 1 >= SP2+r2 -->relay 2 ON
Temperature of probe 1 <= SP2 -->relay 2 OFF
Relay 2 with c2=inv.
Temperature of probe 1 <= SP2-r2 -->relay 2 ON
Temperature of probe 1 >= SP2 -->relay 2 OFF
Mode ON OFF1 (On1) with r0=dep.
Output 1 works as in independent ON/OFF control (Figure 1 and 2), but output 2
works as follows:
Relay 2 with c2=dir.
Temperature of probe 1 >= SP1+SP2+r2 -->relay 2 ON
Temperature of probe 1 <= SP1+SP2 -->relay 2 OFF
Relay 2 with c2=inv.
Temperature of probe 1 <= SP1+SP2-r2 -->relay 2 ON
Temperature of probe 1 >= SP1+SP2 -->relay 2 OFF
Mode ON OFF2 (On2)
Output 1 works as in independent ON/OFF control (Figure 1 and 2), but output 2
works as follows:
Relay 2 with c2=dir.
Temperature of probe 2 >= SP2+r2 -->relay 2 ON
Temperature of probe 2 <= SP2 -->relay 2 OFF
Relay 2 with c2=inv.
Temperature of probe 2 <= SP2-r2 -->relay 2 ON
Temperature of probe 2 >= SP2 -->relay 2 OFF
Neutral Area Mode (nEU)
Relay 1
Temperature of probe 1 >= SP1+r3 -->relay 2 ON
Temperature of probe 1 <= SP1 -->relay 2 OFF
Relay 2
Temperature of probe 1 <= SP1-r3 -->relay 2 ON
Temperature of probe 1 >= SP1 -->relay 2 OFF
Operation in case of error.
If probe 1 fails, the operation is through c3. (See Parameter description.)
If probe 2 fails, the operation is through c4. (See Parameter description.)
In case of memory failure, both relays will remain open.
