Mesa 7i96S, SSR output not work

I have spindle CW and CCW signals connected to out-04 and out-05. Both works fine.

I want control spindle water cooling with relay and Mesa output. I have connected relay to PB3 pins 13 and 14. When I try to control the relay, nothing happens and Mesa output led not switch on.
I bought cnc router used, so I'm not sure, what Mesa configuration I have. I have read Mesa's pinout and it shows HOSTMOT2 and I can find line
TB3-13,14              11   IOPort       SSR              0        Out-00          (Out)
If I try to control output by command "halcmd setp hm2_7i96s.0.ssr.00.out-00 true" and read state by command "halcmd show pin hm2_7i96s.0.ssr.00.out-00" state changed from false to true. Still, output led not lights up and relay not change the state.
I'm totally stucked with this and have no idea what could be wrong.
