6 Operating modes
6.1 Test mode
In test mode, the most important functions in the control sequence are checked and shown on the text
display. To start test mode, call up parameter no. P08 “Test mode” (see section 5.2 for more information)
and select one of the following test modes:
Test mode 1 (Valve test)
Each valve connected is activated in sequence and shown in the text display.
Test mode 2 (Input test)
The signal statuses of the inputs are displayed on the text display.
Test modes 3-5
For manufacturer purposes only
Test mode 0 (test mode off)
Test mode is switched off.
6.2 Down time cleaning
To activate down time cleaning, perform the following steps:
Remove the factory-fitted wire jumper on input E1, E2 (terminals 10, 11).
Connect a free auxiliary contact (make contact) of the fan contactor to terminals 10 and 11. The input
should be operated in isolation.
Set parameter P05 “Down time cleaning cycles” to the required number of cycles (see also section 5.2
“Setting parameters”).
If the fan is switched on, the contact on E1, E2 closes and switches on the cleaning. When switching off
the fan, the contact on E1, E2 opens and activates the down time cleaning. The down time cleaning
cycles set are carried out. The RM-216 CB then shuts down.
6.3 Cleaning via start / stop input (external
∆
p switch)
If the cleaning is controlled via an external
∆
p switch, the isolated contact on the
∆
p switch must be
connected to the start / stop input D1, D2 (terminals 12, 13).
During down-time cleaning, the start / stop input D1, D2 is inactive.
